Can these run in Sli?

[RicoDirenzo]

I have a BFG 9800 GTX+ 1 gb and have acquired a PNY 9800 GTX+ 512mb card. Can these run in Sli with different memory amounts? Will the memory on the 1 gb card scale back to 512 mb (which is fine as I use XP pro 32 bit and the 1 gig is a waste anyway)?

Yes they can run in SLI.

Yes, the 1Gb will be cut back to 512.
