I hated to dredge up this old thread, but I just wanted to point out that I installed the newest build of CloudReady 64-bit (ChromiumOS) onto an A4-3420, that was overclocked slightly to 106 FSB, with a 16GB SSD I got off of ebay for $9 shipped, in AHCI mode, and YouTube 1080P@30 VP plays wonderfully on it. With a single 8GB DDR3-1866 @ 1600, but with the FSB OC, more like 1866 again. Memory timings were manual 11-11-11-36-2T, I think.
1080P @ 60 VP9 stutters occasionally though, enough to be annoying. Unless that my 30Mbit/sec internet causing that, or the SSD's slow random-write speeds. (0.1MB/sec)
