I had an FX 5600 XT that was actually slower than a vanilla FX 5200 (not the 64bit one). It was severely underclocked, so you could raise its core clock quite a bit.
Not quite the same chip. FX 5600 is NV31, FX 5200/5500 is NV34. TechReport has an article here that explores the differences: https://techreport.com/review/4838/a-peek-at- … 5200-and-5600/2
The summary is:
- FX 5600 (NV31) is 130nm, like the FX 5800 (NV30), while FX 5200/5500 (NV34) are 150nm
- NV31 supports lossless color and z-compression, NV34 does not
- There may be more shader power in NV31
The 5600s will generally also have faster RAM (500MHz+) than 5200/5500, so while a 5200 may be able to hit 300MHz+ on the core to try and "match up" with the 5600, it likely will not be able to match memory performance, especially with the lack of color and z-compression. The exception to this is the 5200 Ultra (and Quadro FX 600 PCI) which has clockspeeds more in-line with the 5600 series, however the lack of color and z-compression (and potential differences in shader power) may still give the 5600 an edge in certain settings. I looked for a 5200 vs 5600 review and found both Ultra cards compared by Anandtech:

The 5600 appears to command a healthy lead in many tests, despite the cards having roughly similar clocks (5600U is 350/700, 5200U is 325/650, both are "four pipes").
5600XT is one of those odd cards, like 5700VE, that has a fancy sounding name but performance (and hopefully price) is very much entry level due to the low clockspeed (afaik 5600XT is the slowest clocked GeForce FX) and slow memory. 😵

I think a safer bet in order to not waste your time is look for a Geforce 4 MX...seems to be more in abundance in PCI.
256MB cards, as far as I know and have ever seen, are 128-bit. I know the XFX and PNY 256MB variants are 128-bit (I've owned both). Here's a few listings on ebay:

GeForce 4 MX isn't bad either (back around '03 I had an FX 5200 and MX 440, both AGP, and they were pretty comparable), but there's lots of very cheap 64-bit variants there too; especially if going MX 4000.
I found my thread too:
Some nVidia cards and 3DMark2001
I misspoke earlier when I said this was done with a P4 - it was done with an Athlon64. 😊
