If the Processor your wanting to replace is the one in your sig and you have the cash I'd say go for it. The I droped one in my KT-400 board and these were the results I got. 2 xp test
I'd say with a Kt-333 baord and the ram you have you should get pretty close to these results.
I wanted to go and get the XP 1700+. so i phoned them first. They told me they ran out of stock and proposed me a 1800 instead with the same stepping and for the same price. is it ok or is there a snagg?
correct me if i'm wrong: in theory i will be able to oc the chip just as fast, only it will be oc'ed less.
