GTX580 with GTS250 (PhsyX)

post #1 of 3
Thread Starter 
Well as you can see by my sig rig, I have a 580, and a 250 running as a PhsyX card I was wondering that since I have a MB that supports 16X only when one card is used, and 8X when 2 cards are used, I was wondering if I used just the 580, would I see a difference? Or should I just leave it as is?

Thank ahead of time.

I would run a bench with it set as is and then pull the 250 out and retest. This would tell you right away if you are better with or without the 250 for PhsyX.

This might help great info on this topic:

You'll pick up a couple fps in non-PhysX games, and probably have no net change in PhysX games since the 250 is right on that edge of non-effective PhysX cards. Not to mention you're taking that stress off your PSU, so you'll extend it's life.

I say pull the 250.
