GPU acting screwy

[pro2a]

When I'm playing Civilization V especially when it gets really heavy into the game (lots of units, computer processing AI moves etc...) every so often I get trails and ghosts on the screen. It'll freeze up sometimes when processing the AI moves etc... I'm running it in Direct X 11 since my GPU supports that (The game gives you the option of DX 9,10 or 11). I know my PC can handle the game and then some (Specs below). It can handle any other game I play just fine with max settings... Civ 5 should be a cake walk. What could be the issue? I'm at a loss here. I've also downloaded the current patch and GPU drivers.

Edit: Ghosting only happens when I'm playing Civ. Otherwise my monitor is fine.

Might be a setting in Civ 5 that is aggravating your card. Could be AA or something, not sure. Try turning down features until you get no freezing, slowly make your way up.
