I just got off the phone with a mushkin rep. He said that better cas specs is more important than a higher FSB. I was wondering what others opinions are about this subject, specifically I am looking at Mushkin pc2100 HiPerformance and Pc 2400.. The 21 hi po is dramatically more expensive when compared to the 2400. The rep said it's because the 2100 would give me cas 222 at 266 fsb while the 2400 would give me cas 232 at 300fsb.. ahh i wish i could have both and compare.. Can someone please share some insight with me!!!!
