In ~3 Years, Using GTX 780 Ti as PhysX card

I was just curious as to what opinions there are out there on this. I know that GPUs have been changing pretty fast the past couple of years and will likely see major gains in processing power within the next three years or so.

I have a pretty good system and am currently running an EVGA GTX 780 Ti SC ACX with 16 GB 1866 MHz RAM and an i7-4930K which is great for maxing on games on my TV. I had planned on getting another duplicate GPU in 2-3 years to run them in SLI thinking that the price would have went down enough and the gains in performance would be great enough to make it worthwhile. I also have plans on upgrading to a 4K TV and probably running 2-3 display setup, with just the 4K TV for gaming and the other two probably being off most of the time.

However, I want to max out games of course, and no one can predict how games or technology will be in that time. I could venture a guess that games will be pretty hungry for VRAM for maxing them out at the resolution and even two GTX 780 Tis would probably have a bit of problem maxing them with 60 fps...or at least some of them. More than likely though at that point in time there will be a few options that are less than $1,000 (closer to $700 - $800) that will be the GTX 780 Tis of that time in terms of maxing games out.

So my question comes to this:

Do you think that GPUs will be sufficiently advanced by then to make getting a super powerful card and running the GTX 780 Ti as a dedicated PhysX card worth doing? And even if that is the case, do you think that technology would have pushed the concept of dedicated PhysX cards obsolete?


My personal opinion on this, is that the GTX 780 Ti will be not worth using as a dedicated PhysX card because whatever effect it may have would be minimal. I would think that at the higher resolutions the more powerful GPU would be able to push better fps and the 4K easier while allowing the GTX 780 Ti to focus on PhysX itself. But even now dedicated PhysX cards are getting tossed aside because people say the gains are minimal at best. Besides in three years the standard GPUs may have 4-5 GB of VRAM and the higher end ones might have 8-10 GB. It seems that 3-4 GB is fast becoming the average now, with 2 GB still being made as more of a mid level GPU and 1 GB as the cheapest option of PC manufacturers. Anyway, would definitely like to hear what you have to say on it.

It will not be worth using as dedicated PhysX card for a very simple reason - why stick a massive noisy heat generator that weights a ton inside your case when any single slot budget card will do the trick then?

If you want a dedicated PhysX card - use single slot small budget card - it will give you all the PhysX you will ever need without needing all the space and connectors 780ti will need to function.

PhysX is not a difficult task for a high end GPU, but it will still take some power off it. That's why a good budget single slotter will easily cover all the PhysX needs while indirectly improving your main GPU performance by relieving it of PhysX duty.

I figured that since I already own the GTX 780 Ti, and it seems likely that whatever GPUs are out in that time would be pretty powerful, it would be better overall to just get a beast of a GPU then and use the 780 Ti as PhysX or something else. I doubt it would be worth selling at that time, especially not to sell and buy a cheap GPU for PhysX. Do you think that it would be worth maybe just using the 780 Ti for the 1-2 displays that I would not be gaming on, and using the newer GPU for 4K gaming then?
