Graphics Card Upgrade

[eagleneb]

I'm looking for a new graphics card to run games smoother, my problem is that I realized my current card has a lousy 512mb dedicated video ram. The games I want to run as smooth as possible are World of Warcraft, Diablo III, and Guild Wars 2. Right now WoW runs solid with most settings on High but Diablo III and Guild Wars 2 (beta) are pathetic. So can anyone please recommend a great video card that will run these games around High settings (if you know the game) that my PSU can handle? The highest I'd be willing to pay would be about $250. I can add any additional info if needed.

What I currently have:

The problem isn't exactly dedicated memory, but that the chip just sucks.

Having only a 400w PSU doesn't give you much room to play. You could get a 560ti for 250 bucks and be completely set (depending on the rest of your PC), but your PSU can't handle that.
I'd say you could get a 550TI and be ok. What is the rest of your rig?

I added more info to the bottom of the original post.

Ah so an e6600. Yea I think you should go with the 550ti and slowly upgrade your rig around it. Starting with the PSU.
