KenKun has Good Pts. Also, if you need to pinch some extra outta your memory, with good quality Ram, you should be able to OC it (if your Mobo has MemOC options). I have one machine where I run PC2100 @ 167x2 (basically PC2700) and another where I have OC'd PC2700 comfortably and stabley to around 400Mhz (but dont need to run it that way, so it is back at default).
Go with GoodQuality PC2700... IMO.
