GTS. for single card
HD3870 for a later Xfire option
Agreed. That motherboard will support two HD 3870 cards in Crossfire, even though not quite as well as an X38 (you'll lose about 7% of the fps compared to the same two HD 3870 cards on an X38 motherboard). If you're not interested in Crossfire, the 8800GTS G92 512MB is the best card under $300. It's only beaten by the $400+ 8800GTX and HD 3870X2.
