1. Intel for great processors and they invented dual core and are coming out with 4 core tech next month (and they make pocessors AND motherbords so if you have intel cpu and intel mobo it results in best compatibility)
2. Ballistix for making fast/high performance ram w/ heatsinks
3. Nvidia for CoolBits and the 6800 I'm getting christmas
4. Maxtor cause I've used a really old 8gig from them that worked but its really just hard drives so whatever
