AM2 - these chips arent what they used to be now conroe is out but the prices have come down accordingly... they are still slightly more expensive performance per £ but you save money on the motherboard so it ends up being cheaper
core2duo - these are the best chips ever and they overclock to be a lot faster still... they are a bit more expensive when you consider the cost of the motherboard though
BUT another important thing is that unlike AM2 chips which had ddr2 controllers and couldnt be used with standard, the new AM3 chips will have ddr2 AND ddr3 controllers and will fit into AM2 sockets
so basically the best stuff is
core2duo E6600/E6700/X6800/X6900 - get these if your budget allows, they are all faster than the entire AM2 range
lower priced - the E6300 and E6400 compare to the AM2s so unless you want to overclock (if you do, get one) you will save a bit of money on AM2, and come 12 months time you should be able to get something tasty to replace the chip and not lose out at all... if you think you will upgrade sooner than that youll be worse off on AM2 though
