...integrated graphics? Blech. You, sir, need to find yourself a new video card. I'd search NewEgg for something nice, and if you're on a budget, you can definately find something good enough there. If you're not on a budget, you can pick yourself up a nice higher-line card like a 6600GT for around $150. Or you could go completely insane and get... a 7800GTX for 600 bucks.
As for me, I'm going completely insane. I found it for $530, though!
