GT 640 Dedicated Physx for 680 SLI?

Hi Gurus, I have replaced my Raid 0 Patriot 60GB SSD with Sandisk Extreme.
I can sell my Two Patriot 60GB SSD or swap it with either a GT 630 or GT 640.

The question is Do u think I should sell the 2 SSD or swap it with GT 630/GT640?

My specs is in the left below my Avatar. I mainly play Batman AC, Metro 2033 and Mafia II on an Asus VG278H 120hz 1080p Monitor.

Note: Due to my case, I can only fit a single slot GPU on my third slot.

Tnx Gurus.

 

those are awful physx cards with 2 680. would slow you down most likely

 

i have a 660 ti and an old 9800gtx+

i actually tried running that card for physx in arkham city, this reduced my frame rates significantly, id actually suggest a gtx 660 ti although that'll likely blow the budget.
if anything id actually try running physx on high with your current setup although you most likely wont get the full 120fps of your monitor.

Im actually assuming you've tried this, what frame rates do you get in Arkham City with physx?

 

I agree with tk. So, the answer would be sell your two SSDs.
Iam waiting to see if some board partner will release a single height GTX650/ti
Would a single slot dual height GTX650 fix your case?

Thanks for the advice guys. Do u think a 650 non Ti would be enough for dedicated physx for my 680 SLI?

 

I dont thinks so. The stronger your main card(s) are the stronger the physics card needed.

 

@ Odellot, SLi GTX680 should be enought for a 1920X1080 monitor. What issues are you trying to address with a dedicated physx card?

 

not worth the hassle

 

This guy did test with a 690 and a 640 on borderlands 2.

You don't need a dedicated PhysX card for dual GTX 680 setup.

 

Also the guy who did this test had only a single 680 and not a dual SLI setup. Since you have an SLI setup that GT 640 could slow down your SLI setup.

 

I might have done a bad link. Look at right side for the 690 w/ ppu test.

I'm on a cell phone, so didn't both to see the 690 outcome.
