u could even go with the hk's they r a lil cheaper and are also great. but u try find another set of ram modules that o/c like the hz's. i havent come across any that o/c as well as the hz's compared to the price.
Either one will get you get you to the 1100mhz range basically it comes down to which one is the better deal. Right now the crucial ballistix is tad bit cheaper.
ya we ercommended g-skill so much that they found the need to jack up the price.... but its true crucial is good if not a little better than the HZ, its just not many ppl know it
