Current setup is in my sig...Have to get an AGP card if I were to upgrade which I guess I would prolly lean towards the evga 6800gs. So my question is, would upgrading it to that card futureproof me for say..another year or so, or would it be best to just build a completely new system? Money really isnt a prob but frugality is my middle name . Also, would my PSU be able to handle the xtra horsepower?
