I work for an commercial interior refurbishment company. I have began using autocad architecture 2009 for 3D rendering on the work computer. It copes with the modelling quite well but when it comes to rendering a view of the room i have modelled, It takes quite some time. I know that you must be patient with 3d rendering but i left the computer rendering a 1024x768 res image on 'presentation' preset starting Friday evening...by Monday morning it had only rendered 3/4 of the image. Since then I have added 2gb of ram to the sytem. (4gb total) But I'm sure a processor upgrade will be crucial. Here is some screenshots of cpu-z: We would like to be able to render high-res images so that we have more quality to present....and we also want to move on to 3D animated walkthroughs of a room etc. wich is impossible on our systems on a realistic time scale. e.g. 'overnight rendering' (at some point in the future we would also like to start using 3D studio max) What system/upgrades would you recommend for our needs?
