Re: Upgrade from 5850: which one?
The second 5850 doesn't have to be exactly the same, but I would highly recommend not buying a cheaper card that skimps on the heatsink. Buy a card with a decent (at least as good as stock) heatsink. By utilizing a second card you are going to increase the heat output in your case. The good news is that 5850s don't tend to get that hot. But the heatsink on the card makes all the difference.
