... as to which video card to get.

Building a Shuttle XPC system, model SN45G w/Barton 2500+ and various other tidbits. I just cannot decide which video card to get! I am not a serious gamer, but I do play the following a bit:

UT
Quake
Motocross Madness 2

Kids hammer the computer with simple games as well. Currently, my Radeon 9000 Pro runs everything fine for me. I would like the shuttle system to be better, but I have always tried to limit the video card expense to the low end. Seems the "SE" series of cards sucks for the most part. And I do not think the PNY GeForce FX5200 that I looked at today would be better than my R9000 Pro...

So what do I do guys? Here is whats important:

Quiet operation (XPC will be on desktop)
Fit into XPC
Low cost (as in $175 or below)
Low power consuption
Did I say low cost?

Looking at the following cards, in order of cost, low cost to higher cost:

FX 5200 ($70 after rebate, cheap card!)
R9200
R9600XT
FX5700U


What else should I look at? Would like to stay with a well known company that stands behind its products as well.

What would you buy ?????
Opinions please!
