well, im not so sure, (so let other ppl clear that out) ..but in general wat i think is tat, wen u hv got one card as gtx285, the other subsequent cards (1 or more) shud also be the same as gtx285...
Coz, i now hv gtx280 SSC edition, so in future i think i'll hv to buy gtx280 only (if i wanna make it as a SLi)..

Also, to amitash:
hey dude can u jus post a pic of ur TRUE wen attached to ur CPU, coz i wanna see if tat thing exactly fits onto ur Evga X58 mobo and also how it looks..

Cheers n e-peace....
