Off course you will buy AM2 platform. AMD announced that they will stop produce most of processors for 939. AM2 is present and only future.

If you plan to play games then buy GeForce 7900gtx or Radeon X1900XT as they have enough power for future games. As I read Radeon X1900XT is even better.
If you don't plan to play games in highest resolution (like 1600*1200 and over that) with full AA and AF, then buy GeForce 7600gt as this card is the best buy without any competition!
