I must apologize for what surely will be the daftest questions around, but my computer knowledge barely stretches past the "press-the-key-cross-the-fingers-and-hope-that-the-little people-inside-the-shiny-black-silver-box-do-their-magic" (OK, minus the little people thingy, but you get the point).
I have a 3 year-old desktop PC that has served well in the past for simple graphics work, but it cannot cope with my newly found passion for 3D rendering - it is slow, sluggish and gets stressed as soon as anything with the Autodesk label on it makes its appearance.
Money is tight at the moment so I need to find the most economical way of getting the old boy to somehow cope with Luxrender without either one of us passing out or getting our brains frazzled. I have a friend who recently bought a AMD FirePro v4900 and I was thinking of doing the same, but I'm clueless as to the compatibility with the rest of my PC, and what to do if my PC needs some other upgrading first to be able to take the card. I'll be grateful for any help, advice or a nudge in the right direction.
My PC info: ASRock N68-S, AMD Phenom 9850 x4 2.51 GHz, 4GB DDR2 RAM
