Windows 7: Would like some recommendations on SLI and Pysx

Would like some recommendations on SLI and Pysx

I got 2 new 580 GPUs 1.5GB SLI, but have a manufacturer overclocked 460 1GB. Would anyone recommend my hooking all 3 up and have the 460 be physx dedicated, or should i leave it out (meaning the sli 580's would perform better without it)?

Let me know if I need to give up more information

does this help..?
PhysX FAQ

it sounds like you can use the less powerful card for the PhysX
without losing the speed of the other two in SLi

Thanks Meister. It seems like it will, and possibly the only way to know for sure is to test it out myself. I just wanted to get a good idea of what I'm in for (The gpus are being mailed). The reason I ask is because I've been having some crashing coming from steam's civ5 game. I looked it up and undid any overclocking I've done, hoping nothing is wrong with my 460 card. I think I will try both sli 580 and sli/physx 580/580/460.

I love learning about computers

Try running the game in windowed mode. It seems to be working for me.

2 580's? I would think that would be plenty. Adding a 460 for Phsyx would seem to be overkill IMO.

Yes over kill is good when it comes to graphics. Just make sure your PSU has enough wattage to support all three video cards or you can risk damaging the hardware

Yes, The reason I have such high gpus is so that I can play games on high settings. I won't need to upgrade for a while now. yea.

I have a 1000 watt gold 80+ PSU and if that isn't enough, then I am truely insane for buying those cards

And on a good note, I realize that the bios overclock was the culprit in civ5's malfunction. Sad thing is is that it was a factory overclock. oh well, fast enough CPU i7 3.06

Was playing DAII and couldn't get the highest settings, which drove me crazy. I couldn't even get medium settings and by all accounts, 460 should have handled. so i went a little extreme. Now when a new game comes out, I expect to play it easily on high settings.

thanks guys, I am really excited to try this stuff out.
