I've got the 3400+ in an HTPC with a few drives and a few capture cards one of which is the Hauppauge HVR 1600 that does QAM at 1080i. The 3400+ can't really drive 1080i well at all, so I was thinking of "upgrading" to the X2 3600+ since they can be had for cheap. Does anyone know how much of a performance increase this would be? Can I expect smooth 1080i from the 3600+?
