I have GTX 560 TI asus direct cu II top GPU
what will the performance difference will i get if i do SLI ? will i get extra memory bandwidth ? Is this a good idea to sli two gtx 560 Ti bcoz the other card i am getting for free from my friend ? Can i use another card which is oc edition while first card is non oc edition ?
Power supply : corsair 650 TX series
GPU: ASUS gtx 560 ti direct cu II top (currently )
cpu: amd phenom II x4 970

yea the reason why you dont see that much of an increase is that a better gpu allows you to game at higher setttings while your cpu limmits your framerate, unless you lack the gpu power for your current settings, so their test system was limmmited to 55 fps or so by cpu, where as the 1080p test, there was a gpu limmited perfomance istead of cpu limmited

I've heard that at low resolutions, FPS is a CPU benchmark because it doesn't take much to make the picture (graphics) but to run the game it still takes CPU. Never really tried it, but I do agree GPU has to work harder at higher resolutions. So yes the CPU usage may remain the same (or even decrease) at lower reso.

PSU is fine, but the CPU will bottleneck, the CPU has to work harder on lower resolutions, so SLI is not a great idea IMO.Sorry, incorrect. its not that the CPU works harder at lower resolutions, its that the GPU doesn't have to work as hard. resolution is irrelevant to the CPU.

you will get some performance boost, but not double, because you will be memory and bandwidth limited, but it will be a siginficant diffrence, and yes you can sli oc edition with non oc edition, SINCE ITS FREE, i would say yes, but dont buy another oneThanks for your time Mr.Neil and i have another question - my brother doesn't have money for GTX 780 or GTX 770 so which card would you suggest for him ? He has only 320 dollars and can you explain the link that i have attached plz, in that link in smaller resolution monitors the benchmarks of SLI are low and why is that so ? why higher in bigger resolutions ?
