KK money_man here are the 754 results. These are overclocked, if you want the normal results for either socket again just ask.
CD Ripping - 3000+ 1.30 3200+ 1.36
MPEG-2 encoding - 3000+ 1.30 3200+ 1.30
Image Editing - 3000+ 1.58 3200+ 1.63
Overall - 3000+ 1.40 3200+ 1.44
Doom 3 - 67.7fps 3200+ 67.6fps
PiFast (lower is better) - 3000+ 51.40 3200+ 51.30
AS you can see, the 3200+ actually with overclock further than on the 3000+ on the 754 platform. All the processor were overclocked with their stock coolers until they would not run stabley.
And also, I have just glanced over and it seems the overclocked 939 3000+ will beat both the 3000+ and the 3200+ (overclocked) on the 754, so GET THE NEW ONE!
