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. :rofl

I personally stepped outside the EVGA box and went with the DFI LanParty UT X58-T3EH8 as that was the mobo most used to put up big #'s at HWBot.

Crysis doesn't scale past 2 gpu's the last I knew, an extremely poorly coded game and since EA was the vendor I never considered buying it.

Kal-EL is right on CrossfireX scaling well to 4 gpu's though, in games that are multi-threaded such as the COD series they scale very well with no latency hit as far as I can tell.

Well I only have 2 gpus, but I am amazed by the scaling I have seen in COD WaW. I haven't tried in XP to do a real comparision, but the framerates go far beyond my expectations in vista.

Well with my tri 280s i was getting 71 fps and high 50's average! Chuchnit and i played alot with the setting and anything past 2aa is kill for my rig im thinking ram issues or drivers.

If you are speaking of Crysis that sounds about normal but if you are talking about COD 4-5 then something is either screwed up or SLi is just bad in general and not just limited to dual card SLi. I play at max settings with driver settings at max quality using 1920x1200 res, I limited my fps to 125 but was previously hitting the limit I had set at 250 and averaging around 200 fps.
