I've heard somewhere (don't remember where) that there was a mod, or a way to dedicate one of the cores on a dual-core processor so that it runs as a GPU... Basically, so that you can use some of your RAM and a core instead of a graphics card. I realize that it's not the same, but I'm just wondering how "do-able" it is. Has anyone ever seen a method to accomplish such a feat?
I doubt it's "doable" at all. for one thing, you'd have to do software rendering since a cpu doesn't have any pixel rendering pipelines, for another, you'd have to have a way to connect your monitor to the cpu.
