I'd like to upgrade my home computer to be able to run Revit, but I'm a complete n00b for anything having to do with looking under the hood of my computer and switching out/augmenting hardware. Please help me figure out what components I've got currently, what I need to upgrade, and what potential conflicts will arise.
I have a fairly new HP computer that runs Windows 7 Home Premium on a 64 bit system. System requirements for Revit are here
(you'll need to click the drop-down for the correct system - I will not be doing anything crazy, so the base 64 bit recommendations should be enough).
I'm OK on the monitor and chip as far as I can tell - I have a AMD Athlon II x4 630 2.8GHz processor, and a 1920x1080 monitor.
I know I'll need to upgrade the RAM - I've got 4GB, and need to add at least another 4 (I'd like to add 8, and supposedly can put in as much as 16 total, but I don't know in what configuration).
My video adapter is what might need a kick - I've got an ATI Radeon HD 4200, which isn't really listed on the AutoDesk site (a Radeon 4600 passes their tests, a 3600 fails to display hidden lines, but neither are "certified").
So, basically, do I need to upgrade the video card (is that what it even is any more?)? Will having to do so necessitate other hardware changes to the system? Can I safely just plug in a couple 4GB sticks of RAM?
I can come back in and answer questions as they arise.
