Will these parts be good for my first build?

1.) Yes, everything will work together

The lowest power component would be the processor. It may cause a bottleneck in the system

The highest power is the video card, which may be overkill

The bottleneck won't be incredibly bad, but you may want to downgrade the video card and upgrade the CPU to a Phenom II

2.) Yes, Corsair makes good power supplies, the PSU does have an efficiency above 80.

3.) It will easily last one year if you rebalance the parts

4.)Yes, the GPU is fine, but you may want to consider a 5770 and a better CPU. You can get a PhysX card with your next build, if applicable

5.)Yes

1. The CPU is probably the weakest component of the system. That's an entry-level CPU. I'd pair an X3 or X4 phenom II with a card like that. But, it will still play your games fine.

2. I'd trust any corsair PSU personally. Its specs are really good, relative to %90 of the PSU's out there. It has all types of protection circuitry and .99 PFC. It could be %78 efficient; it's just not %80, so it doesn't meet the certification requirements.

3. Yes, it's good for a few years, possibly even a decade. It depends on how long you run it and if you maintain it.

4. No, you shouldn't overestimate today's GPU's. You might be able to run Black Ops at 90 fps, but crysis at 30. Games vary widely in computational workload. It really depends on the settings and resolution your gaming at. That GPU will run any game, but some will have to run with lower visual effects.

5. Yes, everything is compatible.

1)It depends on what software you're trying to run. Are you rendering in 3ds max or maya, editing on adobe premiere, or playing crysis? Look at the system requirements of the stuff you want to run on it and do a little research to find out it there's an unavoidable bottleneck like there is with rendering (you could get a dual-xeon 6 core setup and still max out your CPU). You'll notice a bottleneck in one of the following ways:

-Your RAM is maxed out but your processor is below 50% and you get a virtual memory error message.

-Your CPU is at 100% (unless you're doing something that would make that expectable like render on 3ds max with mental ray)

-RAM and CPU are both below 75% but your frame rate is crap (if you're playing a game)

2) I address the power supply in 3) but newegg has a PSU calculator. Just go to power supplies and click "Which power supply do I need" and enter in the necessary info. 80+ (bronze/silver/gold/platinum) is about efficiency. It's a good idea if you don't want to waste power, an it also generally helps keep the inside of the case a little cooler. I would recommend 80+ at least but the higher the efficiency rating the more expensive it is so it's up to you.

3) As I said it all depends on what you're using it for. I think spending $600 on a computer you'll only use for a year is kinda silly. How about getting parts that you can use in the next computer too? Figure out what you want in that computer (roughly) and get a PSU that will handle it, the case you want, the mobo you want, the RAM you want, the GPU you want (or 1 of the 2 SLI or crossfire GPUs you want) and one of the HDDs you want? Then in June you just have to replace the CPU, maybe get more RAM, maybe add more HDDs, another GPU if you want, and the only extra part you'll have is the old CPU.

4) I talked about the SLI thing in 3)

5) yeah they will but I don't know what you want them for so I can't say if it's a good build for you. Make sure the optical drive uses SATA not PATA (EIDe)
