Right but lets say given you have a really nice new computer with everything you woulda rigged up on an SLI machine, minus the second graphics card, I'm sayin with few games really puttin the top end cards to the test these days, seems like you could just wait and buy the second card later when there were games that would stress it. I'm askin if without that second card would there be any difference than a non SLI machine with the same specs and the same one graphics card? ... so is there degradation in performance in an sli mobo w/o the second card?
