I bought a 890GX Board, 955 B.E, and 4 Gigs of ram for 220$ as he's upgrading to a 2600k system. He is keeping his current graphics card and crossfiring an additional one (5850), I was planning on either getting a 5870 or 6970, I'm just wondering if it's worth getting a 6970 with the current hardware levels I am going to have or am I going to see roughly the same performance out of a 5870. I plan to OC the 955 on air as well. I don't have a PSU that can support either card yet I'll be buying one when I purchase the card as well so it's really non issue.
