A new twist on SLI

[Leonidas]

The reason why the dual ultras are about even with a single high grade radeon are because it's limited by the power of the cpu.

while i truly deepdown dislike gechoecko the truth of the matter is he makes a point the graphics cards are somewhat limited by the cpu... as in the half-life 2 tests if im not mistaken the x800XT single runs almost on par with the 2 6800 ultras in SLI...

so the lesson is, if one technology is "doubled up" like this it may find a bottleneck within another technology...

They are only CPU limited in some games/applicatations. Any engine that really pushes the Graphics cards, you will see real improvements in. There are some driver issues in some games, but that's to be expected with technology that's not even available to the general public yet.

Also, SLI solutions are not intended for the mid-range user. They're not a gimmick either, they show huge performance increases in many games/applications. Each to their own, anyway, I'm not personally prepared to pay $1000 just for a couple of graphics cards, but some might be.
