I am currently using a 7900GTX for my HTPC. It is my understanding that much of the video processing with this card is done by the CPU, as opposed to the GPU as is possible with newer cards. Can anybody recommend a card for me that will suit my needs? I use my system for video only, no gaming. I have a 1080p LCD connected. I primarily watch DivX rips of TV shows, with the occasional 720p or 1080p TV show or movie rip. I was thinking 8800gt or 9600gt. Would those be good choices? I believe the 8800gt has 256mb and 512mb varieties, would I be able to get by with the 256 or should I opt for the 512?
