Hrm. I wonder how they managed to not need a power connector for that particular card when both the 1900XT and 3870 require one. Was the 2600 really that pathetic a card? ^_^
It's not "pathetic", it's just a different class of cards. High-end cards (like the ones you mentioned) always require additional power, low-end (non 3D) or middle-rate cards generally don't, which is great.
