Turtile: $$$=squat. Like, I won't spend more than $80 on the motherboard, and I've decided I want it to be backwards-compatible with my old AMD Duron Spitfire 750MHz processor, so I won't have to do it all at once. I'll worry about the processor later; for now, I need a new mobo.
Etch: Well, what I'm doing now works just fine on my Frankenstein's Monster cobbled-together machine, so I figure that even if I do more demanding stuff, anything even slightly faster should be adequate. Like I said, I'm only doing relatively light-duty digital editing, and since my mobo has issues I can't wait to save for a high-end system. I'm paying for community college, my car, etc. on $7/hour. It'd take me years. Wish I could, though!
ZeroStrife49: Put me in the "budget" category! Good info though, and may yet be useful.
GuitarFreak1857: I'll sure check it out, if it's cheaper.
Current comp stats:
AMD Duron Spitfire, running @ 751.4MHz
64KB L1 cache
128KB L2 cache
320MB PC100 RAM
350W Antec PSU
AGP slot: ATI Radeon 7000
plus three PCI slots with a wi-fi card, an ethernet card, and a cheap 5.1 sound card.
Basically, I want to reuse everything except maybe the RAM, since the new mobo probably won't support such old stuff.
Gigabite: Unfortunately, the Athlon XP series costs more than I was wanting to spend. I'll keep an eye on it though; maybe by the time I can afford a new processor, they'll be cheap enough. (like, a month or so).
