Yes, I haven't posted in years, busy with life and all that. But for early Christmas, I got five AMD quad cores, and boom: much higher production. So much better than the Athlon 1800-3000s I've been using all these years. So, tell me more about losing efficiency with multi cores. I'm super pleased with my new rigs, I don't see how it could not be worth it. Please explain, Nitrousine.
