Which of these builds is better for gaming?

fx8320 would probably be most cost effective solution of you overclock it. but unless getting the FX8320 for like under $120, its probably not worth buying.

gtx970 or amd r9 390 are great gpus. the amd rx480 is being released soon which will have same performance as the 970/390 for $200.

im lazy, heres a copy paste of previous answer to pc building question that should mostly relate to you.

(essential)

-CPU (runs your whole pc basically. gaming doesnt require a super power cpu. but if you want to do work on your pc, many applications utilize much more than gaming does. many modern cpus have graphics processors built right on them. this means if you are only planning on light gaming, you dont have to buy a graphics card at all. but for any real measurable gaming you want a graphics card)

-Motherboard (connects all your components together. get one that supports what you need it to. like if you want built in wifi, get a board with built in wifi. if you want to be able to use multi graphic cards, get one which supports that. if you want good quality audio when using headphones, get one with an ALC1150 audio codec for example)

-Ram (used to store data of currently running programs. minimum needed is 4GB. gaming PCs its often recommended to get 8GB of ram. 16GB and you will never have to worry about anything ever lol. more then 16GB is useless unless you are doing a specific task which uses more. if you dont know what that is, then you dont have to worry about it)

-Storage drive (SSD-solid state drive, and HDD-hard disk drives are your 2 options. SSD are better then HDD in every way. including speed, power usage, heat production, noise and reliability. the price/GB of space is almsot 10x higher on SSD then HDD. So the best option is to buy a smaller SSD, like 120-240GB for your windows operating system and your software, maybe a few games, and put everything including movies, music, pics and other games on your HDD, 1-2TB+ defending on your storage habits)

-Power supply (converts AC power from your wall outlet to DC power your pc uses. you want to look for 80+ bronze or better, certified psus. 80+ bronze means its atleast a minimum of 80% efficient at AC to DC conversion. this means it will put off less heat and draw less pwoer from wall, so lower power bills. generally crappy psus dont have this efficiency, so anything that is not 80+ should be ignored. the most important spec on your psu is the 12V amperage. its usually shows on a sticker on the side that has 12V. cant go wrong with something from corsair or evga. their lower-tier psus are decent enough quality. a low quality psu will run hot, loud, use more power, and has the chance of catching on fire. not joking. do NOT buy really cheap $10 psus or anything)

-Graphics card (most important thing for gaming. buy the best one you can possibly afford. dont recommend anything less then an nvidia gtx750Ti for gaming. the gtx960 or r9 380, or RX480 in a few weeks, is the sweet spot for gaming gpus in price:performance)

-Case (holds all your components. there are generally 2 types of cases. ones which go for more airflow, or ones that go for more quiet operating. and everything in between. so thats your first choice if you want better cooling, more important for things like overclocking or running high end components in a small case, or a case which lowers noise. i prefer quiet cases. things to look for in a case are possible fan placements [front+rear+top is optimal, and what any case should have], psu location [generally want psu on bottom of case], cable management room behind the motherboard area, and dust filters for the front/side/bottom if they allow fans there)

-Operating system (windows, mac osx [see hackintosh] or linux. linux is free and is slowly replacing windows in msot functionality. many games are supported on linux, but many still are not and require lots of work around and tinkering. windows is still the go to gaming os. you can buy windows 7 for cheap and upgrade to 10 for free)

(peripherals)

-Monitor (used to display things. its basically same thing as a TV. you can connect a PC to a TV just like a console. you can play from the couch with your pc on your tv. people prefer monitors due to they have a higher number of pixels per inch, and come in variants that are 1440P/4K, 21:9 ratio or 120/144hz)

-Keyboard/mouse (required. any keyboard is fine. mechanical keyboards are nice. dont buy a "gaming" keybaord unless its atleast mechanical. non mechanical gaming keyboards are basically keybaords with lights and overpriced. but you will want a gaming mouse. extra buttons are nice and you want something that has a decent sensor. there are guides everywhere)

-controller (required for some games. other then first person shooters, third person shooters and real-time strategy and games like MOBAs, controllers are usually a better experience. xbox one and ps4 controllers are currently the best ones available)

-headphones/speakers (if you want sound. can connect it to home theatre system or any thing that accepts optical cables or 3.5mm audio cables)

-microphone (if you buy a headset they have them already. but many headsets are trash. "usually" its better to buy headphones, then buy something like a modmic or vmoda to attach a mic to the headset yourself)

(Optional)

-DVD/Blu-ray drive (if you are a dinosaur and still use such media. you can install your operating system from a usb drive)

-USB HDD/Flash drive (used for backing up data and/or reinstalling your operating system. id recommend a small 8-16GB flash drive for your OS, and getting like a 1-2TB [depending on usage] usb hdd for backing up data)

-CPU cooler/thermal paste (if you want your cpu to run cool and quiet. the cooler the components operate at the longer they last. getting a tower cpu cooler or AIO liquid cooler also helps direct heat away from motherboard aswell. if you upgrade cpu cooler, i recommend buying thermal paste incase you mess up installing it. as every time you remove the cooler you need to re-apply the thermal paste. buy something non-conductive so you dont have to worry about getting paste on the motherboard)

-extra case fans (to increase case airflow. its recommended to have a minimum of 2 fans. 1 front intake and 1 rear or top exhaust. its optimal to have 2 front intakes + 1 rear exhaust + 1-2 top exhaust fans. even with just 2 fans your pc wont "overheat", but more fans will keep everything much cooler, and allow all fans to run slower/quiter)

(tools required)

-precision screwdrivers (must include phillups/plus)

(tools optional)

-antistatic strap (have never needed one ever. just dont build on carpet and you should be fine 99.99% of the time. touch metal to discharge yourself before building. having PSU plugged in to the wall, but turned off can act as a ground and may help in the event of a static charge)

-magnetic tray (for holding screws while building. makes it much easier. can get them for $2-4)

-magnetic wand/pick up tool (for getting dropped screws or other small metal pieces, can be handy). Also anti-static tweezers can help pick up small things dropped.

-canned air, or air compressor, or blower vac ( like Metro ED500 DataVac ). used to clean dust from electronics (consoles too!). should have one of these 3 things always available. dust build up causes overheating and heat lowers life span of components to all electonics. also good for cleaning keyboard.

-anti-static brush (used to brush off/clean electonic conponents. not really required if you never let dust build up much in first place. but can still be somewhat useful)

Here are some useful links/pages that can help you with any questions or help you may need with anything. pc and pc gaming community is very friendly and helpful, unlike console communities.

https://www.reddit.com/r/buildapc (a subreddit for nothing but helping you with every step from choosing parts, assembling it and troubleshooting)

https://www.reddit.com/r/pcmasterrace (helpful and good community. can answer any questions and also give recommendations. may also get games from a giveaway)

you can use /r/buildapcsales to track part sales. /r/gamedeals for sales on games (steam, origin and gog are all having summer sales or will soon which are some of the better prices on games. 60-90% off). also look at isthereanydeal.com

https://www.youtube.com/watch?v=n2dJvqU2_x4 (video how to assemble pc. same process for any parts you buy)

Its much easier then you think to assemble a PC. its literally no different then assembling anything else (like desk, chair, etc), but this time you have not only a large community willing to help, but also numerous build videos.

There is little you can do to destroy your pc other then smashing it or something. There is little you can assemble wrong (everything only really fits in 1 slot. you pretty much match the slots. just watch video, and then have video open on phone/tablet/laptop while building and you should be ok. the process is the same regardless of what parts you choose)

Build 1 assuming it's also a 7200rpm drive... but you should have the 750watts on it.

Your video card is the critical piece in all of these. 16gb ram is standard, cpu doesn't matter much, power supply depends on the card. Better to wait for the 1070 card and new ATI cards to launch because 970 prices will plummet as people rush to upgrade.

Also you should look at M.2 ssd drives as your boot and main games drive. Stunning performance but not much space.
