Ok so here is a list of the parts: ( I have already bought them btw.)
CPU: Intel Core i5 3330
CPU Fan: Stock
Motherboard: Msi Z77A-GD55
Memory: Patriot Viper 3 8gb DDR3-1600
Hardrive: Western Digital Caviar Blue 320gb
GPU: EVGA GTX 650 1gb Normal
PSU: Corsair Professional 650w 80 Plus Bronze Certified
Case: Corsair 200R
Would this be a bad choice for games such as Battlefield 3, Minecraft, League of Legends, Runescape, Blacklight Retribution, Counter Strike, Dark Souls, Saints Row,Skyrim, and DayZ on Medium-High Settings?
a lot of those are pretty minimal its just BF3, Blacklight, Safety row and Skyrim that might be troublesome (someone correct me if i'm wrong)
It will handle all of those games, maybe not completely lag free when its maxed out but not unplayable either. Its a shame you didn't get 1800/1866 mhz ram but oh well, it'll do. Also if you'd have gone for say, an AMD fx 4 core, you could've spent a bit more on the GPU and maybe got a 660 or even a 660 ti, which would've handled all of those games on max graphics at 30+ fps constantly.
Should be fine but you should have gone for a HD 7770 or gtx 650 ti
Yeah i was going to go online but my mom made me buy the stuff at a local frys which made it cost about $200 more than it should've
