Humppa, if it makes you feel better, I've never seen any problems with my FX5200 and I've been using it steadily for almost 4 years now. I was going to build a new Amithlon box and get a new gfx card, but seeing as I haven't had problems with the 5200, I may just save myself the cash and not build a new one.
@Bombcrater,
What's the Ram limit on Amithlon now? Did you push it to 3GB, by chance, 'cos I'd like to max my ram slots, at least, if I can. :-D
Also, I may be able to donate an older motherboard that supports 2X AGP, if you can get yourself another Voodoo. I'd like to get some sort of 3D accelration, one day.
Shame we can't use QuarkTek for Amithlon.
