Hi, I own a gtx770 and wat to try a dedicated one.

I'm having trouble choosing between 750 or a 650ti.

Thanks!
 
Many would say that it's simply not worth it, and for the most part I'd agree. But you say that you want to just try it. No harm in that, I suppose, if you've got the cash.

Given the choice I might wait for a 750 Ti on sale and buy that; its low power consumption might be a nice thing to have, and its bit of extra power means it may be worth using for longer. The small memory bus may hinder it in that regard, though, as it's never a good thing to have one card waiting on another. I couldn't say whether that's an issue. Otherwise, I'd go 750, I guess.
 
Wait PhysX still exists? Has there been a game where it actually helped in 3 years? (or ever in a lot of peoples opinion).

(This is coming from someone who owned the original ageia PhysX addin card, but Nvidia has managed to pretty much 100% completely kill PhysX)
 
I checked and was slightly wrong, I forgot it was worked into unreal engine which is still being used for a couple of games. But its not necessary in those games (as in doesn't require and gpu to handle the physics, other then having a dedicated gpu for it just adds some more dust particles that youd never notice._

Sell your 770 and get a 780 or 780 ti so you can run higher settings and framerates in EVERY game. That makes way more sense than buying a dedicated card for physx for 2 or 3 games where it will actually have any impact. And even in those its only in a few spots where it will be of any benefit and it still wont fully get the job done. By that I mean there are spots in Assassins Creed Black Flag and especially Borderlands 2 that will take a crap no matter what.
 
Not sure how credible this is since I know jack about nvidia cards, but a coworker of mine said he sold his dedicated physx card because he said you run into performance problems when the two cards aren't clocked at the same speeds since the other card will have to wait for the other to finish. Not sure how true this is but maybe someone experienceef with dedicated physx cards can shed more light on this if actually true.

That is not accurate at all.
 
i have to agree with everyone else....your better off going for a single better card (780) than putting money into another "Physx dedicated GPU" but if you sure thats the route you want to go i figure a 750 do ok.....but really a single 780 by itself would probably handle both by itself better anyway...not to mention you get the benefit when not using Physx games as well....

most people that add Physx dedicated GPUs are likely using something they already had imo....they didn't go out and specifically speed money to do it...there are actual ways of making it work with amd cards as well...i have at least 2 spare nvidia cards in the closet...but i have yet to see a reason to even want to make it work lol...none of the games i play use it anyway

long story short investing in a 780 is a better investment and just sell your 770
 
If your needs (games) warrant a physics card then the 750ti is a great choice. Try your best to get it on sale. One of the tiny ones without the extra power connector.

I agree with everything said here. I was also thinking about adding a 750 Ti for PhysX. But I had an old GTX 570 laying around that I plugged in instead to add to my GTX 780. The performance gains were actually pretty impressive, but the fact that there are only a few games that support it makes me say that spending the extra money on one is not worth it. The drivers will also basically turn off the PhysX card if no monitor is plugged into it in non-PhysX to save power.

If it's an option I would take the money you would have spent on a 750 Ti and the money from selling your 770 to buy a 780.
 
For games that actually used Physx, I got quite a performance boost when I mated my 770 with my old 570. To be honest though, I was quite happy with the 770 doing all the work by itself.
 
What is your current resolution? Have you tried running max graphics with physx enabled?
