Too bad FM1 boards don't work. I wanted the Quad Core 3800 that only came out for testing and not in retail (unless you bought a laptop or desktop with it) The new 65W Quad Cores with better iGPU (though I haven't ran any games on the HTPC yet beyond 16-32bit Emulation) is what I would do, but I just built this sucker, it idles most of the time (NFL Sunday Night Football 1080i, 18%) never goes over 30% usage even watching a BR Rip.
Super Snappy with 1600Mhz memory and SATA3 SSD (60GB). I said I would build a thin client desktop out of a quad core though....
