if you are willing to spend the money for a black magic intensitiy, use the money and get an aver product
avermedia hd dvr for budget and avermedia game broadcaster hd
the hd dvr offers exactly the same as the black magic, for less money and with a better software
the game broadcaster hd is currently the best capture card available, being the only one able to record true 1080p footage (next to the intensity extreme which 0,0001% of all computers can run)
at no point you should consider an HD PVR as its stone age technology with really bad hd capture quality
oh did i mention its extremly overpriced as well?
