I just purchased this PC http://www.gateway.com/systems/produ...80.php#prodBar ($420.) and need to update gpu to set up my first mythbuntu masterbackend (leaving DTV!). Need recommendation for NVIDIA VDPAU GPU? I know I may need to update PSU, planning HD homerun (OTA) & 1212 (cable box) so multiple hd in and out. It seems as the "myth" hardware threads and wikis are out of date for newly released drivers, myth, and mythbuntu. THANKS!
