heard a few things about MSI KT6 ultra and GA-7VT600 Ultra from tomshardware,, but basically want a good upgrade for most likely a good oc computer it also seems the barton 2500 266fsb was the cpu to o t with, but not sure which is best to oc, also money is an issue, i do have a sblive 5.1 and netcard, so they would be not required.....
