Hello Everyone

Yeah as Andy mantioned

The Processor is the item to spend the serious money on then a good amount on the GPU. RedSDK (The rendering engine used in Articad) benefits most from it. I asked Redway (The developers of RedSDK) about it as I was beta testing TurboCAD a while ago that uses the same engine as I noticed monitoring the GPU usage it was hardly being taxed:

Subject: RE: Rendering Performance - GPU

 
Hi Darrel,
 
during high quality global illumination rendering, the GPU is not used (except for the display feedback and some post-processing stuff). Most is done on the CPU which explains why the GPU load is not that big.

The GPU is used in editing materials for the preview of it, this can be painfully slow on my machine with Glossiness above zero. The GPU will be used more in the future I think so do not skimp to much on this part. GPU rendering is used for "Real Time" renders and I know this will become more useful and require a good GPU to get a good performance in this mode.
