well the 940 is a black edition as well, and i should easily be able to hit 3.6 ghz but yes i understand that the 955-965 will be able to OC higher. maybe i will just get the 955 tho, should be able to hit 3.8 ghz with that guy even on air. for now tho i am just going to stay with my am2+ because even if ddr3 is relatively the same price as ddr2, i won't need to get ram right away like i will if i get an am3 board. i guess it would be best to get the 955/965 tho for when i want to swap over to an am3 board and use the full potential of the cpu. i don't want to get myself stuck in a situation where i cannot upgrade motherboards without upgrading cpus.
so am2+ for now, 955 BE now, 5850 now, same ram now, am3 later, ddr3 later.
and im not sure if this dual core would bottleneck the 5850. it would be more based on a game by game scenario, which is really cpu dependent or not
