Re: GTX 480 (825/1100 MHZ) vs. HD 5870 (975/1300 MHz)
Ninja, I think you're right. There's a significant jump when the 5970 is overclocked to 2 x 5870 levels because there's like a 200 mhz jump in memory. However, most 5870s are limited to 1300mhz memory. It's very likely that there's just no benefit to overclocking the core unless there is a bigger bump in memory speed.
