650 obviously, 384 CUDA cores should be okay..
I did a quick Google, are you looking into getting AC3? If so get the 650Ti as it comes with it free and has double the CUDA cores (so better for PhysX)

Hmmm.

 

I might get 650 ti for Phsyx and AC3.

 

Wouldnt it be an overkill though?

 

I mean if I can get by with a 630 or a 640, I would really want to get one. But if they will not perform as great as 650ti, than I will definitaly go with the 650 ti.

I would get a 650 or 650Ti. Less than that and you could be having slowdowns, more than that it's not worth it.

I don't agree with having a dedicated PhysX anyway though. PhysX is overrated.

This, dedicated PhysX cards are a waste of money, there aren't that many PhysX games.
And the ones that do have it play just fine with your 670 doing the PhysX.

I have a spare 460, but I see no point in adding it to my rig... the extra power usage and heat it adds is just silly.

The thing is I am gaming at either 1440p resolution or 3Dvision.

 

Both require more GPU power than regular 1080p gameplay

 

My ultimate goal was 3way SLI, but I downscalled it to 2Way SLI + Phsyx GPU...

 

Again the reason is because of 1440p or 3dvision gaming.

 

Do you guys still believe a dedicated phsyx GPU would not help?

post #7 of 11
No, especially when you're thinking about SLI..
2 cards gain so little benefit, why bother for that 1 or 2 FPS?

Oh right.. the OP has a 670. I didn't even read that!
Yeah, keep the 670 for PhysX and add a third if you need be! Might as well not waste money inbetween on a 650Ti or anything!
I agree that if you have an AMD card or two a 650Ti or similar for PhysX is possibly worth it if you want AC3 or can get it for cheapish and do want to play PhysX games. It's also a good backup card if anything goes wrong with your 7950 etc. thumb.gif

There was a user over on evgas forums that had tested it with up to a 680 if I remember correctly and he found no increase in physx games over just a 640 I think.

Edit: it was a 650 in games but he thinks a 650ti would yield better performance in future games. http://www.evga.com/forums/tm.aspx?m=1768879&high=physx+testing

The 650Ti is the best choice, especially if you are or will be running SLI+PhysX. I am adding a second 670 for 2way SLI and the 650Ti for PhysX, simply because the increase in minimum FPS is substantial enough to be worthwhile to me. Plus, if you plan ahead and stagger purchases, you can get quite a few free games.
