hey I bought a video card two weeks ago that is KFA2 GTX 560 Ti at 950 Mhz. after 1 week I noticed that the game began to slow and laggy, also I noticed in the program called GPU-Z that the core clock goes down to 405Mhz when I play and do not stop at 950MHz and therefore it's goes laggy. So I gave it back to the store and I bought instead SOC Gigabyte GTX 560 Ti. but I got the same problem with it. and I do not understand why that happens.
help please
Thanx for understanding.
