Moved down from a ATX to a mATX board. Only have 4 expansion slots. I have a couple of TV tuner cards and I want to add more USB 2.0 and 3.0 ports to the back. I am using a GTX 660 right now but would like to use a single slot card. The only video I do is some home video with a HD camcorder, retreive HD contents off my cable box with a HD PVR and may edit commercials out of it and record analog TV off my TV tuners. No video games whatsoever. Any decent one slot cards for what I do?
