Which bus? Message-ID: Date: 12 Jun 91 23:52:01 GMT Sender: news@grunt.psy.uq.oz.au (Grunt's News) Organization: Psychology Dept, University of Queensland, AUSTRALIA Lines: 19 I am thinking of upgrading my old 286 machine. I want a fast machine to use as a workstation (with Windows or DV, perhaps even OS/2 or Unix). I want to do some intensive numeric calculations so I need a maths co-processor. Given that, am I better off getting a 386/33 + 387 machine or a 486/25 (I don't think I can afford a 486/33)? Does the on-chip co-pro on the i486 make as much (relative) improvement as the 387 to the 386? (Was that a relevant question?) If I get a 486 machine, should I get one with an EISA bus, or is an ISA bus sufficient? Does ISA = AT bus? Thanks in advance, -- Mike Strasser Psychology Dept The University of Queensland
