Ok i have 2 PNY GTX260's and for some reason in GPU-Z and Evga Precision it says that my cards are running at 300 core clock/601 shader clock/ and 100 memory clock. Yet on the first tab in GPU-Z it says my cards are overclock to 686 Core clock/1479 Shader Clock/ and 1109 memory clock. Whats going on? Im sooo lost! Ps its my first time overclock GPU's in SLI.
