I'm running a Voodoo 3/2K on the ECS K7S5A. Works just fine for UT, anyway. A GF 256 paints a nicer picture, but if you're not A-B-ing the two Vidcards, the Voodoo is just fine. I've never messed with Autocad, so I don't have a clue--except that the Voodoo is probably a bad choice for it.
I've seen the BM's for a couple of 64 Mb GF2 MX-400's that show a ~15% increase in performance over an original 32 Mb GF 256. Whassup with that?
As mentioned, the K7S5A isn't an OCer's dream board. I don't have a problem with that, as the economic reason for OCing Athlons is just about extinct. The sport remains, of course.
My ECS has been rock stable. Unfortunately, I read a review that stated that IBM 75GXP HDD's(I have a 45 Gb 75GXP. Not a secure feeling--at all) make using the "Ultra" setting for your RAM impossible. From what I read on the BBS at
www.storagereview.com , the new IBM 60GXP's are not a good investment. It's time to jerk IBM's chain, hard. I suggest avoiding both the old 75GXP's and the newer 60GXP's.
Some people love/hate every brand of IDE HDD. If I bought one today, I guess Maxtor or WD would be my choice. Ya never know until you have bought 'em! Just make SURE that a prospective Maxtor is NOT a Quantum!
