HTRegz - I might as well spill my system specs.

~$660 for a Dual CPU Workstation (Not the best gaming machine, but not bad either) with these prices that I recall (may be cheaper now):

Gigabyte GA-7DPXDW-P - Dual AthlonMP Workstation Motherboard - $230
2x Athlon XP-Mobile (35 watt) 2400+ - Good overclocking processor - $90 each
512MB Kingston PC3200 ValueRam - Will be run at PC2100 speeds - $90 (ouch - summer DRAM "shortage" inflated this cheap RAM to insane prices)
Vantec "Stealth" 520watt PSU - decent PSU, high-end price market - $100 (vs $150 initial retail)
Vantec "Aeroflow" Heatsink - I needed something small - $30 each



Now, the processor isn't actually supported by the motherboard (and will infact be underclocked a lot when you try to use it). But that's why I bought it...


After some pin-modifications and other work I have both processors running at a stable 2.43GHz.

There is only one system configuration that comes close to this cost vs performance ratio. And those days are nearly gone. Imagine setting up a Dual Xeon system running at 2.8 - 3.4 GHz for $650. Used to be possible, and infact you might be able to do so. But it isn't as easy as it once was...
