I have never OC'd anything before. I am looking to get 2 GTX 460s. I would get an OC'd version, but I like the way the Asus ENGTX460 CU looks and I could OC myself easily I hear. My question is why do all the reviews I read say they only get the memory OC'd to 1700-2100 ish but the OC versions of the cards and GC versions get 3600-4000 on the memory. Can anyone explain this to me.
