I am a light user of AutoCAD. I normally pull dimensions off of 2D architectural and mechanical drawings to do calculations (in Excel) or simulations (in other specialized programs). Then I pull out my virtual red pen and do markups on their drawings to illustrate my recommended changes. On rare occasion I'll open a 3D file for a visual reference, but not often at all. I am probably going to upgrade from AutoCAD 2005 (full version) to AutoCAD LT 2010 when I buy a new laptop. Occasionally I sketch stuff from scratch, but never in 3d, and I don't do renderings of any kind.
Given all that info, I am wondering if I need to even worry about what graphics card my next laptop should have? Would a CAD graphics card do me any good whatsoever? Mostly I just want to be able to quickly open large batches of 2d drawings and start copy/pasting the parts I need into a single file. I'm thinking I only need to worry about CPU+RAM+SSD...GPU is mostly irrelevant for my basic needs, right?
