Wow, sorry... I just came back into this thread after a recent upgrade that was related.
The vcard is a MSI 560GTX Twin Frozr (1gig)
AMD you can crossfire cards from the same series.
So anything in 500 series is my only chance?
It seems to me that there are like 6 different "brands" of the same card.. Nividia, EVGA, MSI, and a few others I dont know.
What happens then?
The chances of me finding another 1 gig here exactly by Msi even though they are right here in Taipei is probably impossible... they get rid of "old" technology so fast over here from their offerings.
The lowest will be 2 gig... and probably 600 series. ( based on the latest flyer of offering I read in the computer area.)
of which you are saying this second card will just be limited to doing math for phys and not really load balancing? SLI is only for people with holes in their wallets I think.
But if I do find a 500 series I will dive on it, Maybe. I would love to know exactly how much stress psy-x (spelling) puts on multi or single vcards.
