Windows Vista HP desktop for capturing tapes?
 

Hello! I have inherited a working Microsoft Windows Vista era desktop from a family from my church and I'm curious as to whether or not it would work within a video capture workflow. It's an HP Pavilion "Special Edition" with an AMD Phenom X4 9550 @ 2.20 GHz (4 Processors, 4 Cores), 8 GB of RAM and four PCIe x1 slots. I have a license for Vista Home Premium Edition and I believe I have original XP installation media in my legacy binder.

So far as I can tell ATI seems to have only made capture cards for AGP slots. Are there any available for PCIe x1 slots?

Thank you for your help in advance!

Yes, that's more than enough for capturing standard-definition video. If it's DV, it'll be a breeze -- that CPU won't even break a sweat. Same thing if the capture device has its own hardware-based compression (like MPEG2). If you're capturing uncompressed video, it should still be fine as long as the software you use isn't horribly inefficient and/or you're using an obscenely high bitrate.
