Here's the system I'm building right now for a friend (he's paying me, AND I get to keep his old parts, hee hee) P4 3.0 Hyper Threading Gigbyte Titan Series 800 FSB (yeah, i know. I told him not to buy Giga-anything, but does he listen? Anyways....) 512 DDR from Kingston. Total cost for parts was around $550. He just snagged a gForce 5700 128MB last week for $150, and with his newer dvd and cd-rw drive, he should be good to go. I figure I'll toss the older P4 (1.8) he's handing over into the renderfarm. :)
