Currently I have 4gb of OCZ PC3 10666 ram on my machine. It's 2x 2gb sticks. They are running stock and the timing are 7.7.7.@ 1.65 volts. Part number is OCZ3P1333LV4GK. I'm looking at the Newegg Corsair memory deal, 8gb DDR3 1600 PC3 12800 for $90.00. Is it worth it to replace my current ram with it or should I just get 4 more gb's of the OCZ that I already have? I do light gaming. My machine specs are in my sig. I don't know much about ram timings etc.. Thanks for any input.
