Well, we all know that the 7800GTX's are quicker than the 6800U's. But just how much quicker? Fortunately, My PC is similar in spec to that of ChrisRay's (except in RAM and GFX, and sound). I got these 2 6800U's about a month or so before the 7800GTX's came out. How annoyed was I :S
PC spec:
AMD Athlon64 3800+ (venice core)
2gb corsair RAM
2 x 6800U's (In SLI, of course)
Enermax noisetaker 600W
2 x 160gb HD's in RAID0
1 x 200gb HD
Windows is on a 40gb HD
I think thats everything importent..
I was considering (and could quite well do) a dual SLI system. Yes, dual SLI. How? you ask me? Well, I have 2 voodoo2's here right now.. but I would forefit my other PCI slots which are in use atm.. Heh
One other thing, that was done at 1024 by 768. Chris, what res did you have it on?
