It looks like a GPU for my HTPC is in my future... I'm still not able to get smooth streaming on video, particularly Netflix (which is a biggie with my family) using the HD graphics on my G620 chip... so I'm researching GPUs... Some (most?) of the lower end GPUs that would be suitable for a HTPC setup have DDR3 memory vs GDDR5 in the higher line cards... is DDR3 adequate for HTPC, or is it worth it to go all-in with a GDDR5 card? I'm assuming the newer cards with better tech will have lower power draw and, therefor, probably be quieter, but I don't know. Any suggestions on a good HTPC card? Must have a full sized HDMI-out... no minis. ...and I don't do 3D. I like Evga/nVidia but I'm open to anyone.
