As has been stated in other threads here, the performance difference between DDR2-533 and DDR2-667 is marginal, at best. Although with 667 the clock speed is faster, the CAS latency is also longer (5). So, although 667 is clocked faster, the higher latency slows it down compared to 533 (with a latency of 4).
Benchmarks might show a neglible increase in performance with the 667, but, in my opinion, not worth the extra cost.
FWIW, I did buy two 667 modules from another ebayer @ $260 each. I'm perfectly happy buying 533 RAM with the faster (shorter) latency.
