I recently acquired a Hauppauge HD-PVR 1212 for digitizing my gameplay sessions. It's an external box, connecting via USB2 cable, and so far I've been using a Windows laptop to do the video capture. I would like to build a box dedicated for video capture, and would like to know what sort of minimum specs for processor and other I should be looking toward? Of course I'll be targeting a USB2 compatible motherboard, with appropriate drivers.
