I would not suspect a professional series card would do better unless you have specific information from the S/W company that says otherwise and gives convincing hard benchmarks to prove it.
If the GPU doesn't even matter much for the 3D SW, just get something cheap like a HD3850 or 8600GT / 9600GT for like $50.
Yes and no, if you are using 2d cad then, sure, just get something reasonable, but if you are doing any sort of 3d work then you will need more.
I use AutoCAD and 3dsMAX daily and, yes, the video card does matter a great deal. Last time I checked the 3d graphics that are on the screen while you are doing your modeling go through the GPU. A big-time CPU helps too, but mostly when you are doing your final renders.
I have not purchased a workstation GPU in a while, I can not justify $1000+ for a single GPU at the level I am working - just not enough poly's to make a difference. FWIW if you want to look at a good gamer card the HD 4870's work better than their Nvida counterparts for most 3d modeling tools.
