Xbitlabs: PhII AM3 + DDR3

Linkage

At most 3-4% improvement going from DDR2-800 CAS5 to DDR3-1600 CAS7. Lower in most cases, including gaming & video encoding - the two main reasons to build a high-end system.

Looks like a 9% improvement in Unreal Tournament 3.

I like to think 1600 CAS 7 should be compared against 1066MHZ CAS 5 so the difference is even smaller.
