I already have a XFX 850w Power Supply, but also the post I previously wrote, I was looking at the 6850, instead of 6950, which is why I thought I could buy 2 6950's for the price of 1 6970, I'm probably gonna stick with the 6970. I'll probably buy 1 first, because I have a 1920x1080 monitor, and i'm pretty sure Crossfire would be overkill, but thats the reason i'm getting 1 first, so If i decided I need more power, i'll pick up a second one. Also Im picking up the XFX 6970 from newegg.
