Everyone should just get rid of sli,
SLI is the most inefficient invention in computer history.
the more cards you add, the lower the performance increase becomes.
when you do 2 cards in sli, you get about a 30-40% improvement oner a single card,
when you do 3 day SLI, you only get about a 5% improvement
the performance overhead of SLI exponentially increases as more cards are added so your getting less and less performance per dollar out of your investment
the reason why videocard companies are doing this s because people keep buying the crap. if you accept crap then you will get crap
when you compare the speed improvement when going from a geforce 5900, to a geforce 6800, the improvement is like 3-4 times more
when you go from a 6800 to a 7800, the improvement is about 1.5 times faster
when each new card, the level of improvement becomes more and more minute
and instead of making better cards, nvidia and ati are seeing that they can make more money by selling 2 slow expensive cards in CF or SLI, instead of making 1 fast card
SLI is just too inefficient, while it helps, it is smarter to just buy 1 card, then wait a month or 2 then but the next gen card that would be faster than of you wet SLI now and it would have cost less
it is like if you get a motherboard that supports 2 physical CPU's if you put 2 single core CPU's on that motherboard and do a benchmark , then remove those CPU's and put 1 dual core cpu instead, the dual core will benchmark higher, even if it is just going from 2 single core amd 64 3800+ to 1 dual core 3800+x2
