im currently using an 8800gt 512MB (Core g92) in my htpc. any card bigger with this one will not fit in the case that im using (nmediapc 5000b). ive noticed that the card runs a bit warm for my liking in this sort of setup, and was wondering what card would give the same performance but run cooler. i dont want to jack the fan speed up because that can be annoying for an htpc set up. any seggestions would be great
