Hello,this is a plea for advice on building a system for modeling. I am using Ashlar Xenon and not doing heavy rendering. I have noticed the newer cheap "professional workstation" graphics cards and am thinking of using the ATI FirePro V4800. (I see that it is a Radeon HD 5670 with different driver and costs a lot more -but don't know what I can do about that.) So I want to build a system because I don't see anything off the shelf I want, but I am new to building and need component selection advice. I want a platform appropriate for this card but happy to spend some extra for a little future-proofing and if I later want to install more powerful graphics option. Everything I read is about gaming -and a little over my head: help?!?
