How is the XFX 7900gs EXTREME?

its very good


overclock it to maybe 560, and it will out perform the 7950gt in some/all games


 

-good choice

Nice. Clock speeds are pretty close to card #28 in these charts, which performs closer to the 7950GT than to the reference 7900GS.

All XFX cards in the top 2-3 models for the category kick arse.

My last few high end cards have been XFX.

Not without the minor issue, same as others, but very good performance for the price.

I'm thinking of grabbing the XFX 7900gs myself.

Yes, that's exactly, and even a bit less, than what's this card is worth, so you have definitly got a good deal with it. At that price it's better than ATI's X1950Pro (200$), and about as fast. If I was into building a budget-mainstream computer and came across such a deal, I'd probably stick with it.
