SLI question here

[KnightsCross]

Can the Nvidia GTX650 2GB DDR5 support SLI and if so what card(s) would be compatible? Would it be a good idea to paid it up with the same exact card or what?

 

[krells]

If memory serves me correctly only the "ti" versions would work in SLI. Either way you would probably be better off upgrading to a newer single card.

No other card except the same EXACT card would work in SLI configuration.

But yeah, I would recommend him/her getting a better single card.
Maybe a GTX 760 or GTX 770.
