The 9800 gt does not support triple SLi the 88xx GTX and the 98xx GTX as well as the 280 do.
Don't talk out of ur @ss please read about the card, the 9800 GT is basically a revision of the 8800 GT wit 55 nm processor and tri-sli Support.
Read reviews ppl
And yes I think triple sli is going to benefit i the future, since games are becoming more and more optmized for multi core gaming.
My quad scales in almost every game. Tri-sli and quad are becoming more mainstream by each coming day, just like regular sli wasn't used at all before, now you can find it in most systems and even laptops.
