Using Your Old Graphics Card To Run As A Dedicated PhysX Processor

I am currently upgrading from a Nvidia 9800GTX to a Nvidia 580GTX and with the current SLI technology can't have them running together because the GPUs and graphics memory is different on both cards. But a configuration that is supported, is using my old card as a Dedicated PhysX Processor.

I wondered wither this would be better than just letting the 580GTX do all the graphics rendering and physics work. And I found this video when I Googled:



In the video he is using a 8600GTS which isn't as powerful as my 9800GTX, but it is interesting to see that the benchmark scores higher when the 580GTX is allowed to do all the work. I don't think it can be stated strongly enough that the results will change from benchmark to benchmark. But as on overall indicator I don't think I will keep my 9800GTX as even if it could conceivably provides a little extra performance if my 580GTX is under extreme graphics load, the extra heat and power consumption required to keep my 9800GTX makes the whole thing not worth it.

Fallout 3 Graphics Comparison Guide

I like This Graphics Comparison Guide they did that shows you what all the game's graphics settings do and wither it might be time for an upgrade.

One of the main arguments about PC gaming is the need to upgrade every six months, but that isn't true if you buy good hardware and certainly isn't true if you are prepared to run a game like Fallout 3 with some of the settings turned down.
