One question... how loud is the cooling fan on it? 
Quieter than on the old MX440 !
Its the FX5800 thats the noisy beastie, The Asus FX5600 has active fan speed, thus it only starts to spin fast when its under load - If I turn off the TV, stereo Mrs & Kids...... I can just about hear the tone of the fan change as D3D or OpenGL kicks into gear....
Working with Paintshop pro, or browsing, it seems to switch the fan off, its not audiable at all.
One thing that tells me my MX was past it, I tried GTA Vice City 8) with the MX back in my machine (whilst I cleaned the dust etc off the fan) with FRAPS, I saw single figure FPS, despite lowering the graphics settings, once the FX5600 was back in, 60fps @1280x1024 was a common sight.
Alas, CFS3 ,when in one of its moods,

::) :( :-/ still reduces the thing to a crawl from time to time, as every other title I posess seems un-affected by this problem, I sadly play CFS3 less and enjoy the rest of my collection, "the way its ment to be played!"
