Re: 7900 3dmark05, 06 average scores?
I think you should be a little higher, but that's not a bad score. Might want to try OC'ng your CPU a little more. We have the same processor, and I got a 13,100 on a single GX2.
Two GTX's in SLi should be noticeably better than a single GX2. I've seen a lot of guys around 14-14.5k with dual GTX's but not sure if they had an overclock on them.
If I were you I'd be expecting 13,500+. It depends on how picky you are about these kinds of things.
