Been looking recently at the possibility of doing a 320MB 8800gts Sli setup as it seems to perform better than a single GTX but costs about the same. I know there are hacked drivers available for the Intel boards, but I'd rather avoid these as they are unofficial. Also know that the 680i boards have had lots of problems. Does anyone know of/have any experience with any good Nvidia boards, i.e. that overclock well and are stable?
