Seems unlikely. Mine's a Prescott with 800 mhz fsb to boot. Only 512k cache though. > > would make the system faster, it transfer data twice per cycle, which > gotta be good for memory tasks?

If this is the reason we are all going to run out and buy Dual channel. (Dual Channel is not the same as DDR, it works on top of DDR.) > > As for video card, not sure if FX5600 is out there anymore.

See if that makes a difference.. Though I doubt it > will.. It should not make that much diff. However, try the mythcommflag benchmark I described in another branch of this thread. Try commflag on SD video while doing nothing, while playing 720p, while playing 1080i, and while playing 720p with xvmc to compare to all the numbers I put up.
