PhysX - Is it worth having a dedicated GPU for running it?

Essex innit!
Right Guys and Girls, in my boredom, I decided to run some comparison video's comparing PhysX on the main GPU and PhysX on a dedicated GPU and the results were varied. I have so far tested Metro Last Light and Batman Arkham Origins but will be doing more (I am a fan of PhysX in games) and showing all the results but so far, MLL gave a small boost to frames but there was a nice bump in Batman: AO and there is a benefit from my testing in running a dedicated PhysX card. There is some caveats of course (when isn't there?) and these are:

Extra heat in the case
Extra power used
amount of games that use PhysX
Need an NVidia card in the main slot

So with those little caveats, it is down to you to decide if it is worth it. You don't need an expensive card like a 970 either and I am sure something like a GTX 460 would do just as good a job. Anyways, here is the results for you to see. My first video compared a 970 on its own as well, just to see how a GTX 970 stacked up against a Titan X.

Metro Last Light

Batman: Arkham Origins

I will be adding more when I have some free time and giving my thoughts on it.
 
Sadly I gave away my last spare GTX 560Ti to my mates boy and as i won the GTX 970 in a competition, I thought I would put it to use. Like I say though, a GTX 460 would do the same job.

Incorrect iv seen comparisons done with older cards + titan x and just a titan x, and the lone titan x was just faster, perhaps the older cards were either unoptimized or the architecture etc, but the older cards seem to run slower than just the T-X now.....ill try to find the links.

Ahhh good to know. The last time I see someone test this, it was on a 460 doing the PhysX and probably a 680 (guessing) and it did well but that was way back, so maybe things have moved on somewhat now.

Literally been stuck at work mate, not had a day off in something like 20 days all 12-18 hour shifts :(

At least the OT will fund a new gpu :D
Should be back more regular on MLG in the next few weeks, not been on bf Wednesday's for months :(

I can understand that. Team MLG ranked 9th in the world now and even the big man 8 Pack has joined us :cool:

The person with 4xTitan X giving advice on bang for buck - I like it :p

I don't think it is worth getting a separate card myself but if you have a spare old card that is up to the job or happen to win a card in competition(!) then it might be worth a go for a couple of games :)

Yer, I just ran it for fun and was quite surprised with the performance difference in Batman AO. I personally wouldn't recommend it but if you do run a single NVidia card and you happen to have a spare GPU laying around and you also happen to love Batman as much as me, it could be worth it :D

Excuse my ignorance but how do you do this?
I've got a 980 in my old case since I upgraded my whole PC last month with X99 and a Titan-x.

Just pop the tatty 980 in the second slot (as if you was running SLI) and then fire up the machine. In the NCP, goto "Configure surround - PhysX" and choose the 980 to do the PhysX and apply :)

Don't attach the SLI ribbon though.
