Look into the 2400M one person got gis to 2.6ghz on Air cooling, which is sick. If you end up going this route, I hope you get a good one. Thats for sure.
I forgot to mention these are OEM so you woudl need a Cooler, but if your going to OC, thats a given. Look into the SLK-900u if your going to get the NF7-s or the 8rda+, but DONT if your going with the ASUS, SLK-900u = dont fit lol.
