I 've got a Dell Demension XBS with a 600HZ chip and 133 motherboard that I recently upgraded to XP. I guess there are a lot more bytes of instruction in XP so it seems to run slower than 98 did (I'm up to 512 RAM). I was wondering if someone out there might have a used 2.4 or 2.6 pentium 4 and motherboard they would like to sell me. I'm figuring hard core gamers are upgrading to 4 gig by now. I'd like it to be someone in Houston who is capable of plugging it in this tower for me also.
