new egg has a sapphire 6870 on sale, and that prompted me to start trying to understand if I can get better frame rates in games. I know my board supports it, although I think both lanes will run at 8x. my power supply is more than enough, not sure if my processor will bottle neck 2 cards or not. maybe the question really is could I get links from some one? ive tried the forum search and im lost in too much information.
