Default Re: 3 way SLI

i just hate to waste a GTX 280 just for graphics,I see that it is faster with just SLI and a seperate physics card at 1600x1200 but they don't mention if you crank up the FSAA and aniso.IMO games just look better with FSAA and aniso.I going to down load that demo and see what I get with 1920x1200 with and without FSAA and aniso.

A third card will add FPS and not like going from one GPU to two. There are exceptions to that statement, like Crysis Warhead @ 2560x. 1920x1200 with high degrees of AA should show some benefits, and 2560x with AA even more so.

I wouldn't bother with Tri-SLi for anything less than 1920x1200 with 8-16x Q AA. A sole exception might be Crysis all VH and that's one game.

If PhysX takes off something like two 285s with a 9600GT for PhysX duty would also be a great option.

Some of you may find the below Anandtech article useful. My big criticism against it would be they limit it to 4xAA use.

8-16xAA @ 1920x-2560x is what needs to be shown for 3 GPUs and up.

The below X-Bit article seems to suggest something like 2 GTX 280s may not be enough for 2560x with 16xAA in some titles-

I found that useing three GTX 280's in TRI SLI at 1920x1200 with high FSAA and aniso helps alot .It not that two would'nt do the job ,most games one is a enough .I just got a good deal on a BFG GTX 280 for $209 and a 9600GT at the time was $129 so I thought it was worth the $80.But no one really needs three GTX 280's .other then I had'nt build me a new complete rig in about Three years and since it is the only hobbie I am able to do I said why not.
