[QUOTE="snewman, post: 86220, member: 18208"] Okay - first results from my upgrade: I went and bought the Gigabyte 6600GT with SilentPipeII - I'm holding off on the motherboard until I can see the results of the new video card. I turned off the HTPC, inserted the new card and plugged it into my 37" LCD (via RGB to start with - I'll battle with the DVI resolutions and overcanning later) and restarted. I then went into the BIOS and turned off the memory allocated to the onboard GPU, then saved and rebooted. That was it - the new card came up, the existing nVidia drivers picked it up and its all running. I just had to change the screen resolution to match the panel (1366 x 768). I can now watch all of my HD broadcasts, whether 576p, 720p or 1080i with no glitches, skipping, or anything. It just worked in the same motherboard with no tweaking. Now I think that proves that the 6150 GPU is not quite grunty enough for HD DVB-T stream decoding. I still need to upgrade my motherboard though, as my 6600GT uses two slots for the passive cooling which eats up one of my two PCI slots. Anyone wanna buy an Asus A8N-VM CSM motherboard? I've also got the coaxial and optical SPDIF module to throw in. [/QUOTE]
