Ok...i am having one hell of a hard time deciding on which memory to get. I am considering lvl 1 or lvl 2 mushkin 3500 black. My main question is am I really gonna tell much difference between the lvl 1 and lvl 2. I am running a barton 2500+ on an abit an7 and will be doing moderate overclocking...at least 3200+ speeds maybe a little more. I dont want to blow all my cash if it isnt necessary.
