I am running a Dual AMD system with a Tyan K7, 2 x 1.2 AthlonMP, 1GB PC2100 ECC REG Crucial, Elsa GeForce 3, 4 x Seagate Cheetah X15 in RAID 0 + 1 on a Adaptec 3200S, a Pinaccle DV500 Video Editing card. I do alot of 2D & 3D Graphics work. I use Photoshop, Live motion, Video Editing software and it does a great job. there is definately a noticeable differance. Even my everyday use on a dual CPU system has improved, I can multitask even better.
