Looks good. Consider a TBSC for your sound card instead of Audigy. Unless you actually
need the extra features of XP Pro, just get XP Home and savea bout $50. A compromise between using the onboard 7VRXP sound and spending $60 on an Audigy, would be to get an Asus A7V333 which comes with very nice onboard sound that's approx. comparable to a SB Live! but without things like EAX and A3D or even get the Abit NV7-133R which is based on the nForce 415-D chipset and has near-audigy level onboard sound. Also don't forget to add $6 for a SVC GC68 HSF from
svcompucycle. Here's the Alternate Intel Rig:
CPU: P4 1.8A - ~$161 from newegg
Motherboard: Abit BG7 - ~$120 from newegg -or- EPoX 4G4A/+ - ~$90/$115 from mwave.com
RAM: 512MB Corsair XMS PC2700 CAS3 - ~$171.50 shipped from googlegear.com
Will cost ~$30-40 more than the AMD rig, but is nearly "guaranteed" to hit 2.4GHz at or near default, with a possible 2.5-2.7GHz potential.
The AMD rig will be a bit faster at stock settings than the Intel rig, but the Intel rig will be faster if you OC, but both are very solid rigs and you will probably be happy with either. It basically comes down to personal preference.
