I am wanting to build a computer that I can use as a pvr and do minor video encoding/editing. I am a new at assembling/shopping for computer hardware like this so any help would be great. I really could use some suggestions on a motherboard and CPU and even a decent graphics card to purchase. I have an athlon now, so I would like to stay where I am comfortable and purchase another AMD. Also, I dont do intense gaming and I am not really sure about sli duel graphics cards. If anybody could suggest a decent nvidia card i would appreciate it. If possible I would like to use my computer as a backup unit/pvr mostly.
