Re: Official Radeon 7970 Review and discussion thread
Moving past 1GB frame buffer will be very beneficial, but 2x6870's is a very powerful setup as long as you don't hit those VRAM limits.
For me it's a no-brainer over the 5870 that has served me well for 2 years. I'm sure a 7970 will do the same.
