Not entirely

Inventor 5, I have not used it for two years.

The more RAM the better.

then why does Thorgal need Dual Xeon setup? makes me wonder

anyway, you are right Sidney

We have just received our new machines which have (2) dual core Xeon processors, this makes for 8 logical processors. My thoughts are that the extra processors do not make much difference when using AutoCAD other than if you are using several different applications running simultaneously. For example: If I pull up the windows task manager while running a command that causes high processor usage, the "acad.exe" application tops out at 13% processor usage (100% divided by 8 processors = 13%) which equates to 100% processor usage for one logical processor and the performance tab shows only one processor in use.

Don't think Thorgal has the octa core setup for AutoCad, but other specific design software.

3D rendering software like 3DS Max should like it

Cinema 4D is another good example.

Ram is key to 3D .... too bad 32-bit max out at 3.5G and 64-bit is limited by drivers. Open GL card will make the work heck alot more fluid, like you said in any game play.

a PC parts vendor told me that I'd need at least a 600W PSU to stay safe (he said that just my 8600GTS alone pulls 125W).

I prefer having an oversized PSU, to avoid instability (vdrop/amps) and have leeway should I need more juice (adding more drives/memory, OC a bit etc etc).

I think (?) that running a PSU well under its nominal max power should make it run cooler (possibly less noisy as well?), safer and perhaps longer lasting than one closer to max spec

A smart PC part vendor will tell you to get 1KW

jmke · 12th September 2007, 21:33

Your 8600GTS will consume nowhere near 125W, rather 100W or less.
Most PSU have best efficiency at 70-80% load FYI

he had nothing to sell, all his 500W+ PSU were sold out

and now I'm stuck until next week

I was talking about the rendering part which is mainly done by server parks.
