I know! If you upgrade your Athlon XP 2800+, send it to me? I'm am pretty much rooting for AMDTI; not because I want Barcy (I haven't seen meaningful benchmarks, just heard meaningless pep talks) or R600/R610/R630 (delayed TOO many times and still without benchmarks).
What I am really looking at right now...
Intel Core 2 Duo E4300 - $169 (waiting till it drops to $120 or so, its similar to the PD805 from a year ago)
MSI P6N SLI-FI (nForce 650i chipset) - $115 (probably won't drop any more, perhaps down $5)
GSkill 1GB Value-RAM (DDR2 667) - $64
Cooler Master eXtreme 430W psu - $35 (yes, cheap, I know)
EVGA GeForce 7600GS - $90 (at least until the GeForce 8600GT/GTS come out (apparently the first specs were incorrect; the GT and GTS have 64-streams and the 8500GT has 48-streams or something))
But anyways... I'd rebuild in my current case, perhaps save up and try for some luck with a generic case/psu OEM deal for the current Celery; if I can ever afford it, I'll make it NAS. That computer doesn't even chug along... I wouldn't even call it crawling.
Still... I'm having problems with the mainboard; if anyone remembers back to 2002, the Intel D845PESV had horrible slot placement; DIMM 1 was too low, so the AGP slot pressed on it. My Uncle maintains that I killed the motherboard back when it had 1GB of DDR in it (it was over summer, so he said it was the heat). Mr. Sabo, the tech-guy from my school, knows all about how bad the slot placement was; he says it was more than likely pressure plus an unstable module of RAM. I say it was pressure. I never did get to run MemTest 86 (I was about 12-13 around then; I didn't know anything in comparison to today, 3 years later). I've been using the same POS system for 4 years. Manufacture date on the system is April 2002; I got it in January when an AMD K-6/2 became too unstable; I told my uncle when it started acting weird, a week later I had my current system. At least it was faster than the AMD and worked pretty well for 2 or so years.
