Lower stock timings = higher OC potential, right?
You say a budget for $130, if you feel faster / lower CL will help then get the fasted you can get for that money.
Will it help your gaming experience, not one bit, zero, goose egg. It will give you bragging rights and nice benchmarks to tell your friends, that is all. What I am trying to get across to you is the smart money go to 1600/9 for the best bang for the buck.
1866 with the prices now a good buy and will give you a bit of overall boost/ CL9, 1600/CL8 is also a nice small step-up. But above that and the money for the performance is not worth it, as the frequencies go up the CL means less.
I think your MB has more to do with OC ability than the memory itself, the power and etch work for timing. That is why it is easier to OC 2 sticks than 4.
