i dont see why you would run a 64bit dc cpu and sli on a 64bit board, in 32bit, yes xp64pro left some things out.. but really uses the ram and system to its fullest,, but depending on what other devices you run, you will surely have driver problems,, so i have to ask, can you not afford vista 64bit? , it runs great,, especially with the ready boost and improved prefetch,, plus you will get the full 64 bit performance.. really noticable in ram scores, and to those folks that still use xp32bit on a modern 64bit system i just say.. c'mon make a back up and get on with it.. you are only running 32 bit cuz your lazy and/or cheap...
go for the gusto, go 64bit
