Dedicated physx

#1kill2thisPosted 1/7/2014 3:43:24 PM
Does anyone on the board run a dedicated physx card? I'm just toying on the idea at the minute, currently using a GTX770 from what I've read (a lot of conflicting information fwiw) I should be looking at a 560/650 as the minimum?
Am I also right in thinking that even though my board doesn't support SLI it'd still work?

It should be fine so long as your secondary pci-e is at least a 4x lane. I use my 670 as a dedicated physx right now until I get my second 770. It works quite well but it is wasted power and heat for normal usage. Just finished batman arkham asylum, played a lot of ac4, and am mostly through metro last light. I don't really feel drops with physx in those games (aside from towns in ac4, which have way too many smoke stacks).

Overall its not worth buying a card for but if you have one sitting around its alright.

Thanks DV8 appreciate the input, I don't have one lying about but I'm eyeing a 650 on ebay for 40 ($60?) so investment wise it'd be minimal.

That's the type of thing I've been trying to find although there doesn't seem to be anything on the 6/7 series.

Lowest I'd go is a 650 but I'm not sure if that would be a hindrance for a 770. Depends on the game I imagine and in AC4's case you might be hurting performance. Again, not in a position to test and as you've already mentioned, results of such tests aren't easily accessible online.

Tried researching online a bit more, only thing I could really find was comments from 770 owners stating that a 650 and even a 660ti actually hurt framerate when used as a dedicated physx processor, I much rather have been able to find benchmarks with proven figures, but i think at the minute I'll hold off.

For a while I had 2 Gtx 560Ti in sli, it got very hot and loud so I decided to replace that setup with a Gtx 680.

When I got the card I tried one of the 560Ti cards as dedicated physx but the results was very underwhelming.

I tested Arkham City and Metro, both showed on average 1-2 fps improvements vs the Gtx 680 doing everything alone, EVGA Precision X reported around 5% gpu usage on the dedicated physx card.
So it really wasn't worth it.

Some day I'll try the Gtx 680 as a dedicated physx card now that I have a 780Ti though I doubt there will be better results.

From my experience, it's not worth it if you already have a fast card, the 770 being a re-branded 680 it's fast.
Maybe you would see better scaling on low end hardware but that's just speculation on my part.

If you have a high end card there's typically not a card worth buying for PhysX. The only thing worth it is if you're buying an even higher end card and don't want to sell your old card.
