can my computer run high end games?

yes it can

but only in medium resolution

you should have quad core processors to play in high resolutions

8 gb ram is good but pentium g NO!!!!!!!

it is not that important you have 2 gb or 4 gb graphics like gt 630 which has 4 gb ram can not play games as well as how a 512mb hd 5850 can play games.................

you have lga 1155 so yes get an i3 3220 or i5 3330 etc.............

read the stuff below and if you dont have a nice gpu get hd 7850 or gtx 760 and for cheap ones go for gtx 650 and hd 7770.................

5.Graphics card

-There are two main gpu company's nVidia & AMD..........

-AMD cards are cheaper than nVidia

-nVidia cards are expensive but they perform slightly better than AMD

-AMD HD 5450 is worst amd card & Geforce GT 210 is worst nVidia Card

-In GPU 64bit low cards,128 bit mid cards,256bit high end

-Dont compare any cards by its memory or how it looks...

-In AMD cards 1st digit defies the sereies last 3 defies performance....

example:AMD HD 4,5,6,7 series 400+ very low,500+ medium,700+ high,800+ ultra

example:AMD HD 4850 would perform twice better than AMD HD 6450

-In nVidia cards 1st digit specifies the series and last 2 the performance...

example:Geforce GT 2,3,4,5,6 series 10+ low,30+ medium,50+ high

example:Geforce GT 440 would work twice better than Geforce GT 610

-some cards work on 300w example:gt 210,gt 220,gt520,gt610,gt 620,hd 5450,hd 6450,hd 5670

-some cards work on 400w example:hd 6670,gt 440,gt 640

-some cards work on 500w example:hd 7850,gts 450,gtx series.....

Yep

Yes upgrade

definite you are able to run it properly, the image card is likewise sturdy on your video games, the dual center i3 which already enabled for hyperthreading can help your pc to encode image and memory quicker and it may do 2 job promptly in each and every cores (2 cores + 2 digital cores)...pretty sturdy gaming rig. The 32 nm center i3 is cooler than the 45nm structure

yes you can run high graphic pc games

before running, it is safe to know min & max requirements of that particular pc game.

You upgrade your PC then definitely high end games will run into your pc.

Upgrade your processor, I don't even know what the heck that graphic card you have is or you didn't type it all.

i think u have enough specs for playing high end games!! thers no need for upgrade

Upgrade your CPU and GPU then you are golden.
