560ti + 460 dedicated PhysX?

[NunsNAmmo]

I'm currently in the middle of designing a new rig for myself, and I've decided to go with the GTX 560 ti, however; I recently was able to boost the total budget for my rig and I was considering getting a GTX 460 as well and using it for PhysX. Are there any driver issues / bottlenecking that might occur if I do this?

In my opinion a gtx460 for physX is a waste. There is also a limited number of games that maximizes physX. Just save the money and maybe buy another 560ti in the future for SLI.

Agreed. If you play any of the few games that support PhysX, just buy a GTS250. The GTS250/GTX260 was found to be all you need to max PhysX if you can't do it on your single GPU. The 560TI is probably fast enough to handle PhysX all by itself.

I'd just grab a 570 instead and then SLI when you can.

Don't get a 460 for PhysX. Too few games use it and those that do can manage with a 560 Ti alone... Mafia 2 is maxed out with all PhysX on my 560 Ti and it's butter-smooth. If you just itch to have a separate PhysX card just for the hell of it - which I totally understand, its fun to fill all the slots on the machine and enable all kinds of stuff! - then find a used 8800GT or something similar to take for free from a friend or get a really wek card that will be fine for PhysX, but that's a waste of money, IMO.

Any thing less than a 9600gt is going to be far to weak for physx and any thing more than a gtx 260 is a waste. A 8800gt is more than enough for most physx games while a 9800gtx/gts250 is the sweet spot. Remember there is a load cap for physx thanks to the drivers so it can't use the full power of the gpu. 40-50% depending on the card and driver installed.

Thanks, that was going to be my plan for my 9400 GT if I didn't need a beefier card for PhysX, I wont be doing anything else with it once I replace it.
