The only thing you lose going with Ati right now, is VDPAU. In exchange, you get lower power consumption, more features (3d capabilities, triple-head) and better performance than any Nvidia card you could buy at a comparable price.
If you wanted a Linux HTPC it would be best to go with a low-end Nvidia just for VDPAU. In all other cases, an Ati card is a far better investment.
