It's an old card though, I'm wondering about how much life it has left in it. If it were me, I'd go for the a new card, not an old card. But in the end, it all depends on your budget. It would be tough to compare the 7900GT to the 4670. The 7900 was a top of the line card, whereas the 4670 is a mid range card. But mid range cards have improved so dramatically over the years that today's mid range cards are as good as last year's top of the line cards (more or less).
