Why!? Doesn't SLI scale very poorly at 4.
Because I want to, not because it'll give me a power level over 9000.
Also thanks .but like the others i am curious why you want to go with 4 of them since if i recall correctly diminishing returns will hit hard on those 3rd and 4th ones. making it not seem worth the hassle nor the cost of it.
Cost isn't much of a problem for me. And yes diminishing returns do factor in but Quad-SLI can improve performance in a variety of scenarios/games.
