Question about SLI

Hi guys, I am hoping to get a gtx 460 for christmas and I have a few questions.

My first question is if I will be able to do SLI with this card and my current card, a GTX 275. I have seen somewhere that people have done this with like one card doing physx and the other everything else. Is this possible? If it is, how could I set this up?

Also, will my 750 watt power supply be able to handle all this?

Thanks!

Using the 275 as a Physx card, yes. Running them in SLI, not going to happen. SLI unlike Crossfire (across a limited number of cards from the same class; low, medium and high end) requires that both cards be the same; 275 with 275, 460 with 460, etc.

Sorry, that's what I meant. How would I set it up as a dedicated physx card? I go into the nvidia control panel and set it up, right? What would I do with drivers?

Physx drivers come with the graphic drivers, so they get installed automatically. If you have both cards installed, then just go in to the Nvidia control panel, and in "Set Physx configuration", it will be set to "Auto-Select" by default, but just set it to the 275, and away you go.

Okay, thanks . Do you think my 750watt power supply can power these two cards?

A GTX 275 is way over-kill for PhysX.

I know, but I have it, so why not use it?

This is true but if it were me I would sell the 275 and save up the difference and by another 460. JMO.

As for your power supply it all depends on if it has enough amps on the +12v rail(s)
But you have a quality power supply so I don't think you should have any problems. Fabe
