Some good information here, as always. My issues with ATI/AMD are tied to their drivers honestly. Neither brand is perfect, but I'm personally just ready for a change.
Seeing as the game I'm "aiming" for is Guild Wars 2 and not out until August 28th, I think waiting to see if the new mid-level Nvidia card is out this month is probably what I'll do. My issues with the oc'd 5850 have never been performance, it's a great card, it's more about drivers issues and my general annoyance with AMD in general. So, I'll wait and see what the next few weeks hold. Thanks guys.
