At costco? That would be tossing quarters, and hoping they come back down General rules of thumb I have observed: intel cpus are better than equ dated amd's, my old quad core phenom was phenominally bad at latency-test. 100+ microseconds. New 9th gen 6 core i5, 4 or 5 microseconds. Till kmail beeps the chassis speaker, then its 200 u-secs. Nvidia video cards being driven by nvidia drivers are horrible, returning 2 or 3 milliseconds, the nouveau driver may not be as fast for video, but it doesn't lock out the irq's either, so its actually quite a bit better. But linux drivers pushing an ATI card were usually best. ATI is now part of AMD but haven't checked the numbers there in several years. So far, nothing beats the intel atom powered D-525-MW mobo for good latency and more than enough cojones even w/o a mesa card to software step. But they've been discoed for quite a few years now, so the only place to get them is ebay, and I'm a little shy about paying 20 to 50 bucks more than new for used. I have mesa 5i25 cards in both of mine now, with 7i76D daughter cards. However, I am pleasantly surprised at how well an rpi4b is running my sheldon lathe. > > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
