Again, the faster your RAM is, the less capacity you'll be using. Thus lots of RAM is not all that usefull. If you want to get past 2.6ghz, your going to need some type of special cooling system. Such as advanced air cooling, or a nice WCS. With a 3000, you better be happy with 2.6ghz. I even think 2.6ghz might be pushing it a little. But with a winchester core, i have faith.
I suggest OCZ RAM. G Skill is really expensive, and used for the most extreme OC.
