From ATI to Nvidia

When you spin the view it tries to redraw everything, which is impossible in real time. So it drops some stuff. On a faster CPU it will drop less stuff. Which means it will be pegged even if it were 20 GHz on a complex enough project.

Yes Fedor, I have noticed that it drops more stuff on larger models as I pan and spin. But smaller models (very small for my 2Ghz), that don't come close to pegging the CPU while panning and spinning have a very smooth 'real-time' feel to the spin. While larger models that drop parts while spinning are not so smooth. Mind you, I typically work on small residential models, not highrises. So I guess I'm wondering where the performance bottleneck is and what is a good balance between CPU, RAM, and video card. My models are small, so RAM is not an issue. It seems I can make some performance gains with more CPU horsepower. Aside from excellent OpenGL support, can gains be had from a video card with a higher memory bandwidth? (I realize video RAM is not so important). I'm looking at upgrading my workstation soon and your insight into these matters is highly appreciated. Thanks! BTW, I'm not complaining that Revit is slow, just wondering how I can get the most performance for my $$$.

Ahem. So it pegs. So what? Look at your experience, not the monitor.

Good point

Not much from video card at the moment.

Performance monitor is helpful with RAM though. If you use it up, you start swapping, which slows you down. If Commit Charge is frequently greater than Physical Memory, it's time to upgrade.

Overall, yes, CPU is your best investment. Especially if your concern is not spinning but interactive editing. Right now there is little reason for you to go 64 bit, but it's up to whether you want to cough up the extra cash.

Thanks for the info Fedor!
