I want your opinion considering 2 GPU given below as i'm gonna recommend one of them for my friend since HD 6850 is out of stock:
1. ECS GTX 560 (non Ti) : do you think ECS is trustworthy.............??? = 15,500 BDT
2. Sapphire HD 7770 OC = 14,500 BDT
Both of the are 1GB GDDR5, Anand Tech shows that GTX 560 is clearly better than HD 7770, in all games the GTX 560 gives 6-20 FPS more. The GTX 560 has 256-bit memory and HD 7770 has 128-bit memory.
Anand Tech benchmark:
But my doubt is that the 7770 is OC-able, so do you think it can take on the 560?
What PSU do you recommend for GTX 560?
