Is this a video card problem?

[Plutoburn]

Monitor suddenly loses signal while playing game, the tower still has power.
Restarting computer but only works in safe mode, monitor loses signal when the window's finishes the load screen.

I am using the EVGA GeForce 8800 GTS 320MB that is factory overclocked.

If it is, which video card should I replace it with? (Budget $350-400) Currently using a Asus P5K mobo with Intel Q6600.

I would suggest getting the latest drivers and monitoring your GPU temps. You could be overheating. Doesn't that card have a limited lifetime warranty with EVGA? I would focus on fixing what you've got, since that card is still decent, even with the relatively anemic VRAM.

That said, a budget of $400 would get you top-end card right now except the GTX 295 or the Radeon 4870 X2.

Yeah, seems like a overheating problem to me as well. Check your GPU temps.
