I just bought a new Gateway AMD 6000+ PC to use as a small HTPC. I do DVB Satellite TV and needed a faster CPU for HD. The PC has a 8500GT GC in it, and I cannot seem to get it to output video to my Plasma TV VIA HDMI. I am running Vista,2 gig RAM, 500 GIG HD, and from what I gather Nvidia disabled the ability to have different content running on each screen at the same time on this card. (mirroring)

The question is, what card currently supports this mode? I am looking at at ATI Radeon 2600 XT and it says it DOES support two different sources indepenently of each other, I was just wondering if I was missing anything with the 8500 GT.
