I came up with this, that graphics card will run most games on medium, some on high. It should do you well, Has a reliable PSU.

in my opinion i would get a new cpu, gpu and add another 2gb of ram. what kind of gaming do u plan on doing? BF3 and modern games or wow and things like that?

nvm i saw the games u play. all can be played on your system but bf3 in which i would go with something like these. give u a few choices on each. going to go with amd bc u do have a budget and those are 90% of my builds.

cpu
1: http://www.newegg.com/Product/Product.aspx?Item=N82E16819113286 139.99 and turbo's at 4.1, with good cooling it can hit big oc's.
2:http://www.newegg.com/Product/Product.aspx?Item=N82E16819113284 179.99 on amazon.com and aslo the cpu i use and its just awesome for the price. stock 4.0ghz and can go over 5.0 with good cooling real bang for ur buck.
3:http://www.newegg.com/Product/Product.aspx?Item=N82E16819113287 only 4 core but reaches 4.1 just like the 8350. gaming dosent use over 4 cores so i'd spwend a lil less on cpu and put the extra on a gpu for high end gaming especially in the games coming out soon like bf4 and such. new black ops.

Motherboard chouices:
1:http://www.newegg.com/Product/Product.aspx?Item=N82E16813128514 won tomshardware award and can handle any amd cpu
2:http://www.newegg.com/Product/Product.aspx?Item=N82E16813157262
3:http://www.newegg.com/Product/Product.aspx?Item=N82E16813131874 the one i'm using and it just has too much to list and its awesome. easy to oc anything and plenty of room for any upgrade u can think of in the future

GPU your only playing on a 1080p monitor so u dont need a 7970 or 680 or anything top of the line and u wouldnt utilize the gpu if u bought it so go with something a lil cheaper. my thoughts would be these:
1:http://www.newegg.com/Product/Product.aspx?Item=N82E16814202024 awesome gpu and p-erforms a little lower than a 7950 for a good price and will play anything on 1080p on max setting
2:http://www.newegg.com/Product/Product.aspx?Item=N82E16814127667 keeps very cool so lots of room for oc'ing in the future if u need it
3:http://www.newegg.com/Product/Product.aspx?Item=N82E16814150588 great cooling and lifetime warranty
4:http://www.newegg.com/Product/Product.aspx?Item=N82E16814202026 great cooling and performance

i picked the parts i would choose personally if i were u. i dont know the size of your case but if its not a mid atx or a full atx i would say go ahead and grab one for 30-70 bucks and look for cooling and room for future upgrades. if u need any help with that message me and ill be glad to help u pick one out.
