The p35 ds3r has highest o/c, lol
Actually its the second highest right behind its sister board. But OC'ing is not the end all be all to performance either. You have to look at a lot more than just OC'ing ability.
There again, it all depends on what is most important. Ironically, the 680i's with the newest bios did better on gaming benchmarks than the P35's. I am looking for that review as we speak.
