Ah! Thanks for the clarification on the 10-bit. I was somewhat confused. For what I'm doing, I'm not sure I'd need a 10 bit display pipeline.
Also, I'm getting a gaming graphics card because, even though I don't currently game, I have in the past and will probably do so again.
I'll look at Western Digital Red vs. Black again--I notice some of the Reds are on sale.
Thanks again to all, I very much appreciate it.
