My old machine and I are destined to part ways sooner than later. Unfortunately, the pocket book would much rather it be later. I have come into the possesion of a 6 month old Athlon 64 XP 3200+ Socket 939 and would like to build a new computer around it. I would also like to reuse as many of the existing parts I have as Possible, which include: 40 gb WD HD AtA 100 160 gb WD HD ATA 100 2 Kingston Dual DDR PC 3200 512 Nvidia Geforce 6200 AGP 256 mb I know switching out the hard drives would be better, but these are fairly new and have a lot of data on them. Also, do I need to buy a copy of Windows xp 64, and will my exitsting software run with that. The biggest thing I am trying to acheive is video editing (I,m using Pinnacle's Studio 9 plus) and actual DVD burning. Any suggestions regarding a motherboard and anything else would help.
