I was looking at an upgrade in ram from my 4g of team dark 1066 5-5-5-15's, and yes im keeping my mobo and yes im useing Xfire, im only lookign at replacing RAM and CPU, ok then, yeah also these vipers that im talkign about are the green heatsink ones not the black, also it seems its goign to be very hard 2 get my hands on them over here, the G.skill that you guys have been testing i found at a shop in my city, costs around $350(AUD). i think that most of the users here r US but hey, to put that in perspective the Q9650 is goning to cost $485(AUD), anyway still wondering if the g.skill hould be the way to go.
