Ok, you can read my current specs in my sig. It's time to upgrade one last time--in about a year or so I will be replacing the whole system, but I want it to have reliable parts, as it will likely become an in-house or web server... So here's the options: Single 1.8ghz Powerlogix for $319 Single 2.0gHz Powerlogix for $369 Dual 1.0gHz for $295 Dual 1.3gHz for $395 EDIT: 2.0gHz option added back on finding a 100mHz bus option Both the singles are the 7447as, and both the duals are the earlier type but with the 2mb of L3 cache per processor. Advice? Opinions? This thread is actually going to help me make the choice, the biggest part of which is really how much the speed difference versus the L3 cache is worth (i.e., doing heavy CS2 and light to medium video and audio editing, is it worth going for the L3 and dual, is there going to be bottle-necking on the 100mHz bus at speeds as high as 1.8/2.0, etc.). Thanks!
