i run Solidworks and Pro-E. Solidworks on an Asus P4C800. bought both of them a year ago because i thought i should learn them. i learned that i like Solidworks.
that system had 2 GB of low-latency Mushkin, with a 10% OC. recently upgraded to 4 GB of OCZ DDR Platinum, though it's only recognized as about 3.2 GB. the extra memory makes a difference, you don't have to re-boot as often.
the Pro-E machine is on an Abit IC7Max. no overclock. not a big pro-E fan, yet.
as far as buying Solidworks approved hardware, i didn't.
System Suggestion - Intel
950 CPU, 3.4 GHz, Dual Core, $300+
Asus P5N32 motherboard, very good power processing circuitry.
memory - Patriot low-latency DDR2
hard drive - Maxtor SATA 300 GB 7VF300 or 6VF300
video card - Asus 6800 GT PCI-Express or faster. in any case, nVidia.
as far as the "ATI Fire GL", one place i worked at about 8 years my workstation always had a "late great" Fire GL video card in a Dell Xeon workstation. My nVidia 6600 with 256 MB RAM is just as fast, for these purposes (modelling & rendering, not gaming). $139. not recommending that card, just saying it's as fast as the Fire GL cards i spent many years using, for industrial strength solid modelling.
System Suggestion - AMD
Denmark 175, 2.2 GHz dual core, $500+ but they should be lowering the price in a week or 2 to match Intel's massive recent (wonderful
🙂 price cuts.
Asus A8N32, same power processing circuitry as the P5N32. crappy place for the reset button
memory - 2 of the 2 x 1 GB OCZ DDR Platinum kits. short fuse on the rebate, got to send it in QUick !
