Dead video card?

For a few months, when there is a lot of black displayed on the screen I've noticed there are random pixels throughout that stay red, blue or green.  When I scroll on the page, those pixels will bleed in the direction that I scroll.  Eventually I could have almost solid lines of blue, red, or green across my monitor.  It's gotten a lot worse though, because now my monitor will start to flicker off and on and eventually freeze.  If I have music playing it will continue to keep playing until I get a blue screen saying there is a hardware issue. 

I've been ignoring it for awhile, just because I haven't wanted to go out and get a new video card.  I think the one I currently have is a GeForce 7900 GS.  The problem is so severe now I can only be on it for 5-10 minutes before it freezes again (I'm typing this up on another computer).

I googled this problem a while ago, and I thought I remember finding a couple threads on various sites with people having the same problem, with the same video card. 

So I need some verification, I guess.  The problems I'm experiencing are due to a busted video card, right?  And, what video card should I now get (I remember a few months ago I asked the same question about new video cards, but I'm not sure if anything has changed in the video card market.)?

Thanks dawgs.
