Hi, I 've ATi 5750....and 'm looking for upgrade...MY cpu spec is i5-750 H55 MoBo 4 GB RAM-- VENGEANCE 500 watt PSU ---COOLER MASTER XTREME 5750 (current ) 1 GB V.card I play at 1920 x 1080 res...and PC is only used for gaming... I ve choosen 7950/7870....I would like to know if my stock (not O.C ed) i5-750 will bottle neck my graphic card........also are there other graphic cards which can cost less, I can use, i want to play at ultra settings......also any better option in nVIDIA.... tnx.....
You'll be fine with that CPU imo. Those are both solid choices, you could go nVidia but it offers less bang for the buck, I'd only suggest nVidia if you need cuda or prefer any of the brands. Some games like WoW or GW2 might be limited by your cpu however. Still I think a GPU upgrade would net more fps than cpu.
Assuming you have CM eXtreme Power Plus 500W, you might want to change that as well. Safety reasons. Seems to be a pretty crappy PSU. i5 750 is fine. Though, overclocking wouldn't hurt. Unfortunately that's not possible with H55 mobo. NVIDIA only offers better price/performance and better drivers along with tech like PhysX and TXAA. Get HD 7950 if you plan to overclock it.
Better price/performance? Lol no Better drivers? Possibly, can't comment on that but can't complain on AMDs drivers either. PhysX: http://forums.guru3d.com/showthread.php?t=372293 Yeah. Cuda might be worth the extra money you spend on nVidia if you need it.
