Hi im looking to buy some ram but want to know which is better 2x2gb 800mhz(or higher if its possible at CL4) CL4 or 2x2gb 1066Mhz CL5. Which is better and why? This is my first build, but i know thaM lower the lantacy CL4 is better then CL5 and the higher the Mhz is better. But which combination is better, for performance and espcially gaming.

Would the first option of ram be better as you could over clock it increaseing the Mhz up to 1066. Would there be any disadvantages and would this be easy for a first time PC builder and overclocker?

Thanks
