I've been trying to track differences, if any, between the brands for the 4870. So far, this is what I can tell are their unique features or omissions. I'm only including differences, not components that they all include like a Crossfire connector:
Visiontek - no power connectors, lifetime warranty. HardOCP had reported that Mass Effect was bundled in the box but has since been confirmed as a mistake; no Mass Effect included.
Sapphire - includes 2 6-pin power connectors, full copy of 3dmark06, 2gb USB memory stick (for a limited time, according to HardOCP and Fudzilla), PowerDVD 7 and Ruby ROM 1.1, 2 year warranty
PowerColor - no power connectors
HIS - no power connectors, screwdriver
Anyone care to add or correct. Don't forget the 4870 needs 2 6-pin power plugs to operate.
