autocad inventor and I7 3820 and firepro v5900

post #1 of 2
Thread Starter 
I'm currently running a i7 3820 and a fire pro V5900 on windows 7 all on SSD and I when I use autocadd inventor for 3D modeling it maxes out the cpu in now time and is to slow for my liking, my questions is would I be better off upgrading to the I7 3930k or upgrading the graphics card to a dual V5900 or a V7900 or possibly switching to a NVIDIA Quadro? It seems like I may just need to upgrade the cpu as I can move the model around in cad just fine it just lags when i start to add things to the part drawing. so I'm thinking the 2 additional cores would help in my situation ????

Depending on the version of inventor you're running, it might not help upgrading the video card. Since about 2008, inventor has been using Direct 3D, not open GL. Most likely you're running in "Realistic" mode in the newer 2012 / 2013 version, and if that's the case, you just have to accept that it's cpu limited. It doesn't use the d3d for rendering in that mode, it uses cpu cores.

Given your setup, the only thing you can do is upgrade to hex core, sell the firepro, get a gtx660 or 570 or something relatively cheap. If you are using other software that renders in open gl, then keep the firepro and grab a hex core cpu. (3930k)

The other thing is, in the main inventor is a single thread application. It responds best with overclocked cpu's, because it's only running on a single core 90% of the time. Not until you raytrace does it start up the other cores frown.gif. Guys who are loading up massive assemblies (14GB size) are using 2600k's overclocked to 4.5GHz with 32GB of mem, and have found that's the best way. (I know - enterprise situation and overclocking is a sin, but whatever works I guess)

Maybe oneday they'll activate multi threading for assembly loading/constraining/framework. Who knows. Autodesk are not the most efficient organisation.
