nVidia 7800 GTX either single or SLI. nVidia 6800 Ultra either single or SLI. 7800 is top of the food chain, until Crossfire becomes mainstream. Get the absolute best computer system you can afford. The photofields in G3 require less computer power than the fully-enabled G3 3D environments. You WILL have to get a serious gaming machine to utilize the sim to its max. No ifs, ands, or buts...been there, done that.
