my specs are 8Gb 2x4 gskill ripjaw x series 1333 ram FX-6100 3.3Ghz 3.7Ghz Turbo 6 core EVGA Nvidia GTX 750 Ti FTW GPU
550W PSU and for some reason everyone that I see talking about the 750Ti always says that you can only run games at medium setting well I for one disagree. That card my friend (with my setup) has let me play every one of my games new and old at high/ultimate mix settings with smooth gameplay and barely any stuttering. On world of warcraft I get 80-120 fps sometimes rarely will it ever go to 50 and thats only when I am fighting a world boss and there is 40+ people casting spells and doing there thing. for other games like Far Cry 3, Assassins Creed Black Flag, Call of Duty Ghost, all of the Dragon Ages including Inquisition, Wolfenstein the New Order, FFXIII, Aion, Tera, Tribes Ascend, Star Craft II, Metro 2033 and Last Light, SimCity 2013 and the new The Sims4, Dead Island and Dead Island Riptide, Dead Rising 3, and a few more graphics intensive games I cant recall but uninstalled. I played every one of thoughs games with very smooth gameplay and no stuttering but keep in mind my monitor is a little out of date so I run all games at 1280x1024 resolution but with all of thoughs games I have no problem playing and running also the EVGA 750Ti FTW runs very cool I have never seen the temp go above 52 celsius
So as far as that build goes from experience with the fx 6100 which is a step down from the 6300 and the GPU I would say that that build is pretty good but I would downgrade the PSU to a 500 or 550 just to save a few bucks
