Here is the system I am considering building to do video editing. This will be a highend system that will most likely only work with WIN2K (because of the promise ata100 6 channel raid 5 controller) to run Premiere, After Effects, and Photoshop. The price difference between 256mb DDR and 512mb DDR is insane. We have everything else we need. Any recomendations? 1.4 Athalon and ECS K7VZA $225 or Dual 1.2 Athalon and Tyan $625 1.5GB PC2100 DDR Ram $600 or 768MB PC2100 DDR Ram $110 Matrox G450 32MB AGP $90 Promise 6ch ATA100 Raid $350 6x WD 80GB 7200 ATA100 $1140 (450GB Raid 5) DVD-R/RW/CD-R/RW $800 DVD 16x drive $50 Rackmount Case $250 Total 1.4 Athalon 1.5GB $3505 Total 1.4 Athalon 768MB $3015 Total 2x1.2 Athalon 1.5GB $3905 Total 2x1.2 Athalon 768MB $3415 *all prices from www.pricewatch.com
