I've seen used dual Xeon HP xw6200s advertised for less than half the price of a comparable dual-core PC. (Dual-core sounds nicer, but is it worth the extra $$$?)
But... some of the ads say the xw6200s come with 64-bit XP. Will my Matrox RT.X100 work with 64-bit XP? I'm less worried about the suite of Adobe apps-- though they might not get any 64-bit advantages.
Anyone using 64-bit XP for video editing?
If there are compatibility problems, is there such a thing as an "upgrade" from 64-bit to XP SP2?
