I'm looking into one of these cards for a future computer setup. I was wondering what is the best overclocker of both flavors. I did obtain a msi gf4 ti4200 64mb (which i heard is one of the best oc'ers) when building a friend's comp. I went straight to 300/600 and it was stable (could go higher, didn't try yet cause the ps blew out), but on an overclocked agp bus at 80 mhz ( the mem backed down to 580 ). I'm kinda surprised that the gainward w/ 3.5ns is not the best.
