"So does Core 2 need high speed memory to shine? The answer is a resounding no!
On Intel Core 2 pure synthetic memory bandwidth benchmarks show a 30+% increase, but this does not translate in a noticeable performance bump in games and applications, where the increase, at best, is ~6% and this going from cheap high latency PC3200 to expensive low latency PC6400, and while these expensive modules do take the performance crown, their lead over the mostly cheaper PC4200 rated sticks is smaller than 3% in real world benchmarks
So it doesn’t matter much what memory speed/timings you buy, the value line will suit the Intel Core 2 system just fine, but do keep one thing in mind, as in our testing we found performance actually decreases a bit going from PC4200 (533) to PC5300 (667)!"
