Although you might think that this is now an old card (I dont think retailers stock it anymore) I would still advise you to get one if you see one on the cheap, or on ebay.
I have been running this card now for around 1 year and a half. Frankly, It's been great to me. It was very expensive at the time, being new architecture, but boy, does this thing perform!
I have been running this with a 22" monitor @ 1600x1200 resolution, and frame rates in even the most modern games are still exceptional!
I had this thing running dual screen at one point, too. And frame rates were still good.
If you are looking to get a card that will play tomorrow's games today, then this isnt the card for you. I would suggest getting an 8800, as they are DX10 ready.
However, if you are looking to pick up a cheap high-end DX9.0c card - Hey Presto! This is great.
It has better specs than the 7600's, and is a lot cheaper than the 7900's, as the 7800 was discontinued on release of the 7900.
So, my advice is that if you do see one of these cheap, and your looking for a high end DX9 card, get it. It's great. It isn't overly large, and doesn't get extremely hot, its stability is astounding.
It is also easy to install, slot it in your 16x PCI-E slot, install the drivers, plug your monitor in and go!
The problems I have had with mine are:
One of the capacitors on the card fell off.
I'm not sure if this was my fault or not, but sometimes on startup, desktop doesn't show properly.
Other than that, I have had no problems.
It can even run modern games on high graphics, a year or so on from release!
