dual video cards is 100% necessary to see crysis maxed out in dx10, and even the 8800 ultras have a hard time with it. Usually sli is pointless in the first couple months of the release of a new model. Usually one single new model (high end) card will max all games without a hitch. Towards the end of the year (like now) the cards struggle for a select few ground breaking games. 2 years ago it was oblivion. Last year it was…I dunno. This year its crysis. And im sure there will be one next year to make nvidias 9 series useless by a high end gamers standards.
But to stick to the thread, I had an EVGA NF68 680i A1 and got my e6600 to 3.6ghz stable. Best overclocking board ive ever owned.
