I'm getting quite good results with a 8800GT card, although, given the
current prices, I would suggest going for a 9800GTX.

If you want to test out the double-precision support of the new cards, a
GTX 260 could be a good choice, provided the power supply has enough
juice for it, and provided it fits in your particular 1U slot. Keep in
mind that both the 9800GTX and the GTX 260 coolers take up two slots.
