Currenty I have a GTX 670 and will be getting a 970 soon. Borderlands The Pre Sequel comes out tomorrow and it has a PhysX option and it will be my main game. Should I keep my 670 as a PhysX dedicated card? Or should I sell it and buy something smaller and cheaper like a 750ti for a dedicated card? Would a 750ti produce less heat? Because sometimes my 670 gets kinda hot (Around 70 celcius). If it produces less heat then I'd probly go for the 750ti.

The 750Ti will definitely be cooler since it only consumes 60W thus the cooler temps. It is weaker than a 670 but I don't know if that's relevant or not.

Unless you smoke cash for cigars, get the 970 and keep the 670. Heck, with the cash saved, get a 980.

Well I was going to sell that 670 and use it for the 750ti essentially getting it for very cheap.

Id sell the 670 .... the change from 670 to 970 is only a two tier upgrade and save the slot for a 2nd one in SLI

I don’t recommend upgrading your graphics card unless the replacement card is at least three tiers higher. Otherwise, the upgrade is somewhat parallel, and you may not even notice any worthwhile difference in performance.

I won't ever be getting a second 970 for SLI because it's too much money for me since I'm going to University next year. Also, from what I've seen the 970 is a substantial upgrade from the 670. That's why I'd rather get a PhysX dedicated card.

No different than a 570 to a 770. And money is exactly why I recommended it

You can extend the life of a PC for 2 years or more with a second card. Your new PC won't be viable by the time you graduate with a single 970 ... add a 2nd card which will be less than half as much money 2 years from now and you'll be able to use that PC for gaming past graduation. Two of my kids did and the 3rd is halfway thru

So basically I should just scrap the idea of a dedicated physx card and just save up for 2 970s? Or would 1 980 be better? I have a 750 watt psu so would two 970s still give me room for ram and hard drive upgrades?

No..... 970 is just fine for now ....when ya start feeling like it's not keeping up ...18-24-30 months down the road, get a 2nd one ... in the meantime if ya want a PhysX card get a cheap 640 or something

The great thing is that you already have the GTX 670, so you get to try it out as a dedicated PhysX card before making your decision. The GTX 670 will be a better card for PhysX than the GTX 750 Ti, but maybe not enough to make a difference. Also, the GTX 670 is a relatively power efficient card (not in relation to Maxwell of course). In the end, I wouldn't get anything less than a GTX 750 Ti for PhysX, however.

Any $65 nVidia card can handle PhysX duties .... nVidia says "at least 256MB of local onboard graphics memory and at least 32 cores will be able to accelerate NVIDIA PhysX"....even an old 220....tho I'd stick with something newer 6xx or 7xx

Gotta check some benchmarks Jack. A weak card with few CUDA cores and low clock speeds will slow down a top tier card like the GTX 980. I honestly wouldn't go lower than a GT 640, even then a GTX 650 or 750 would be preferred.

Borderlands 2 can bring a single card to its knees once the heavy PhysX kicks in. I'm thinking of putting in my old GTX 580 to help out my GTX 780 Ti for some of those intense battles.

So you are agreeing with me ...almost, I said the 640 you the 650 .... but you can get by with less if one drops on ya lap.

I almost always agree with you, and I am here as well. Except for this part:
"at least 256MB of local onboard graphics memory and at least 32 cores will be able to accelerate NVIDIA PhysX"....even an old 220'

Basically, I know you know this, but you wouldn't want to drop a whatever-old-220 into a system with a GTX 970 in it. That would be a recipe for futility. In addition to my links above, Linus had an enlightening review, although it left a little to be desired in terms of viable recommendations.
