there was a review somewhere in d net...sometime ago...i think at xbitlabs

if u can get more than 260 @ 2-2-2-x ,it has the same performance compared to 275 at loose timings...but d problem is...its very hard to get more than 250 at very tight timings...

afterall,in real time everyday use,can anyone feel d difference rather than benchmarking?(please correct me if i am wrong)
