I have an HTPC that I occasionally like to play a game or two on, but must also be near-silent. Currently I have a 9600GT, rated at 95w by NVidia, with a large passive cooler (Accelero S2) I attached that's been working great for 4 years now. Thoughts on if the 7750s might fit within a similar heat/power envelope? It'd be nice to update the video on this thing, it's fun for flight sims and such on the 1080p projector and I'm sure the E8400 processor would match up performance-wise.
