You may need to add a discrete graphics card to that, but everything else should be fine. I'm finding a note on the Ceton Support Page that the InfiniTV6 PCI-E does not support tuner sharing, so while you can watch anything that been recorded using your XBox 360 as an extender, you would not be able to watch live television from it. You'd need to go with the InfiniTV6 Eth (external device).
first of all I have a gaming pc but I also have a amd fm2+ dual core I can use the gaming pc but it would be better if I could use the dual core. Video source is cable and I will be using xbox 360's for wmc extenders.
These are upgrades of the Ceton InfiniTV4 Quad tuner. Until I know the full system specifications of your system(s) (as earlier requested), I can't make a recommendation.
