Quad SLI has been a flop since the first iteration of quad sli back in the 7 series gpu's I think it was. Its a driver problem that they've never really solved.

Gotta remember how sli works, SLI splits the on screen dutys in half while tri-sli splits it up three times and quad sli well, four times. Thats alot of paralell syncronized processing going on. I'm not an expert but I'd reckon this is where the driver struggles in its dutys.

Honestly, the performance advantages between sli and trisli vary from gen to gen. It all depends on if you're overclocking and how much. For gaming, it depends heavily on the game playin nice with the drivers as well.

Makes me wonder if they should be work on a firmware update vs newer cards and drivers!

Well, then they would stop making money altogether as the 8800ultras would still be the top performers of the day

Nah, they gonna stick it to us every 3-6 months like usual and play catch up with the drivers as they prepare for the next launch.

Yea im begining to wonder if i made a big mistake switching from the tri 280s to the 295s. So far only difference is ive lost some frames in some games and picked up in others. But now i cant play crysis at all! freakin crysis

Usually the single card "dual pcb" setups perform really well but when paired with a second nvidia x2 card, things get squirly. I'd overclock one of the cards and see about gaming performance. With my 9800gx2's I got a nice overclock and better game performance from running just a single card as opposed to quad slo.

You could always sell off the second card to pay for a nice waterblock, wc loop.

Incidentally, the ati x2 cards don't seem to suffer the quad sli blues.

I have had a spare system for the vid i just needed the blocks i have one and waiting on the second then ill put both blocks on the 295s at the same time. The only issue i have is i got the same performace out of crysis on one card as having both enabled??????:confused:

Are you sure quad sli was enabled? You would think performance would be a little better, but then again if the drivers suck, then you get the big suck.
