Dual card and dual monitor question

post #1 of 7
Thread Starter 
Hi all,

Currently I have a GTX 570 video card that powers 2 monitors using DVI connections: a 1680x1050 display and a smaller 1280x1024 display. I like to have the 2nd smaller monitor available for looking at temps while gaming and also for quick access to google for looking up gaming answers for MMO gaming. I recently acquired a 2nd video card (a GT 240 nvidia card) to use while my GTX 570 card is being rma'd. So I'm wondering if there's any advantage to installing both cards and using the GT 240 card for the smaller display while the GTS 570 runs games on the main monitor. Would that help with FPS, etc.? I'm thinking it should help because it relieves the main GTX 570 card from having to drive the 2nd monitor.

You'd think this topic would be a simple google lookup, but so far I haven't found this particular scenarios covered in anything I've found, and I just spent an hour searching!

*edit* And NO they are not going to be in SLI, they will be completely independent cards.

From a couple posts I've read I think I can use both cards on different monitors without SLI as long as I use the same video card driver. That is not a problem since both are EVGA nvidia cards and use the same driver. The GT 240 is not capable of SLI which is fine because I wouldn't want to run such mismatched cards in SLI anyway for obvious reasons.

I did find in my research that you should NOT use an additional lower video card dedicated to PHYSX processing because you get worse FPS than just using a single higher card.

You can only SLI two/three cards of the same type.So The GTX 570 and GTS 240 cannot be connected in SLI.

GTS450 only allows two way SLI
GTX 460/560 only allows two way SLI
GTX 470/570 allows two or three way
GTX 480/580 allows two or three way

Yes you can use both cards in a non-SLI situation to drive a monitor from each card. It will help keep the temps down on the GTX 570 for sure.

And if you are going to go with a GT 240, do not use it as a dedicated physx card, it will be less powerful than using the 570 for both rendering and physx.

Thanks for the info! I increased your rep for your response. I'm going to do some benchmarking and looking at temps both ways to be sure, but it's good to know I'm thinking down the correct path.

And yeah, I know about the dedicated PHYSX issue, I just posted about that here: http://www.overclock.net/nvidia/1029...l#post13691054

Spot on. Just don't use an SLI bridge, and the drivers should sort out the rest. It'll definitely take the temps on the 570 down as well.
