I'm building a computer. I have an MSI K9N2 Diamond motherboard with an AMD 9950, 4G of Mushkin 1066. The motherboard does not have onboard sound, so it comes with a PCIe sound card, eating the only PCIe x1 slot, leaving three PCIe x16s. I want to get a tuner card (I'm looking at Hauppauge's WinTV-HVR 1800 MCE), but I'd rather not use up another PCIe slot if I can help it; I need one for a SCSI boot drive and one for a graphics card, and if I put the tuner in the last one I'll have hit the wall. There are three PCI slots just sitting there looking lonely. My question is whether the difference in speed between PCI and PCIe is going to make any difference with a tuner card that will be used to record HDTV off the air and capture analogue video from a stone-age Handycam.
