Hello. I currently have a high-end ATI card in my system and a very lonely PCI x16 slot.
I am looking to purchase a Nvidia GPU to use as a dedicated PPU, but I want to spend as little money as possible. Having searched Newegg, I see that I can get low end cards from 8xxx, 9xxx, or 2xx series for ~20, which would be great if one of those would be able to adequately handle modern physics needs. I have two questions:
1. Are those cards capable of handling modern physics processing as a dedicated PPU? If not, what is the cheapest card that you would recommend?
2. Would those cards be able to handle physics processing in the foreseeable future? (how do physics processing power needs scale with time?). If not, what is the cheapest card that you would recommend for that?
Also, as an aside, do you know if those hacks to the Nvidia drivers that let them run with an ATI card still work? They don't seem to have been updated in a while.
