Then a new card with 2GB would be the best bet?
I didn't expect to ever use more than one monitor, so I never planned that far ahead.
Wouldn't my board be okay, just a tight fit and be a little close on the cards?
Yeah, you're right, it is, I overlooked that.
I appreciate all your help. I think I'm going to go with a 7870 single card. It appears to be the cheapest option and one of the better solutions short of buying a new board and card.
