Aw nuts...

So that 2.4GHz Pentium 4 I was talking about last time turned out to be a 2.4GHz Celeron, and the motherboard only supports up to AGP4X so I went with the GeForce3 instaed of the 7800. The thing's functional, but man, does it suck at multitasking! Certain revisions of the motherboard support Prescott CPUs (5.A, 5.B, 7.5), but not mine (7.1). I haven't heard anything back on that craigslist posting about the motherboard, so it looks like I'm stuck with:

• 2.4GHz Celeron
• Biostar U8668-D (PCB 7.1)
  
• 1GB DDR400 (Dual Channel)
• 64MB GeForce3 Ti 200
• 80GB + 160GB IDE
  
• Sound Blaster Audigy
