ok it does work but my advice for who ever want to SLI with flight simulator X
dont dont dont, those youtube videos showing sli are fake
its not stable at all and it doesnt make a diffrence
it actualy works faster with just 1 card rather than 2 cards sli
only Crysis worked perfectly with SLI. also windows xp 64bit doesnt seem to work
unless you have the exact same ones I did everything "I am a super computer expert so I would try everything"
so, if you want super graphics get the gtx2 don't SLI its just not worth the time
