[RndTbl] new ECC computer options

The AMD FX series is definitely "enthusiast" as are the AM3+ boards that
support it. The AMD Opterons are the server-class models. The FX series
definitely supports ECC; I use them with ECC with no trouble. The FX-9590
(8 cores) is the top of the line (unlocked so you can play with clock
multipliers), but is rated to run at 4.7 GHz with Turbo mode to 5.0 GHz.
Priced around $300. Most AM3+ boards are $100-$200 with a few outliers.

Though if you wait for the Ryzen series, performance will be even better.
