I'm looking at upgrading relatively cheaply from my old 939 setup (San Diego 4000, 4x512 GeIL Ultra DDR500, Asus A8N-SLI Premium). So I've picked out the motherboard I want and the RAM i want.

Well then the problem comes down to the processor, an old 6400 or new 7750 BE.
6400: Fastest dual-core stock AMD has ever made, 2x1mb L2 cache, but 90nm and apparently runs extremely hot. Plus is more expensive and getting harder to find.
7750: 65nm, 2mb shared L3 cache, supports DDR2-1066, but is 2.7GHz as opposed to 3.2GHZ and only has 2x512kb L2 cache.
First off, I usually don't overclock but after reading about the 7750 BE I think I'd be willing to give it a shot especially if it is as simple as just changing a multiplier. Second, I'm not a fan of the 2x512kb L2 of the 7750 BE, but then again it has 2mb shared L3. But then a question arises that I am ashamed not to know the answer to, what is the exact benefit of the 7750 supporting DDR2-1066? My guess was: 7750 allows you to run the DDR2-1066 at its native speed without having to overclock anything, and in a sense would make up some of the difference in the loss of some of that L2 cache and mhz by going with the 7750 BE.
Could someone shed some light on this for me to help me understand the benefit of the support of DDR2-1066 with the 7750 and in doing so help me make my decision on which to get? Thx.
