If you feel like it, back everything up (remember any saved games can be lost too... found that out the hard way... gotta start MOH: PA from scratch :thumbsdown: ). Since they are both Nforce4 chips though, you should be alright. Even the nforce driver is the same, so most likely all you'll need to do is let windows re-detect everything and re-boot. By the way, NICE SYSTEM!!! :Q :thumbsup:
