anyway, you'll most likely need some sort of after market cooler on which ever mid-high range card in that case, so i'd just look for the best deal.
I imagine it would be because he wants a single slot card. For what it's worth, I imagine that your video card isn't the issue in terms of performance, if this is still accurate:
Shuttle SN45G
1GB Kingston HyperX pc3500 cas2
2 Maxtor 8mb cache drives
Samsung 352-B combo cdrw/dvd
Leadtek Ti4200 Vivo
AthlonXP 1.47@2.12Ghz, 211mhz FSB
...you are cpu limited, and you probably won't be able to squeeze much more out of this pc no matter what video card you install. That being the case, I would suggest keeping your current setup (and put up with the noise for a bit), and then upgrading to a PCIe system with a faster processor. The next generation of cards will be out soon, and you already have a powerful video card, so I would either wait to get a next gen card or at least benefit from the price drop it will bring to the current gen.
All that aside, if you just have to get a new single slot card right now, both newegg and monarch have good deals on the AIW X800XT or a regular X800XT.
