Trust me, you didn't pay much for your video card. My XFX Geforce 6800 GT cost me about $850 and change when I bought it two years ago. It's quickly reaching the end of it's lifespan. She's getting real hot when I'm doing heavy gaming. It's gone over a 100 degrees a few times.
Sad thing is, the card hasn't gone down that much since I bought it. It's almost as pricey. Ah, well. Such is the price of PC gaming. Neverending upgrades.
