750 for physx?

[eyetrip]

Yeah, I know, dedicated physx card hardly ever gets used, etc, etc... still..

Would a little 750 go well with 980 ti sli? Or too weak?

If that too weak, gues a 750 ti would be too...

If they are, what's about the best minimum card as dedicated? Don't want to spend a lot, so going up to 960 prices might be out.

 

[eyetrip]

Well, I decided to try a 960

I know, most will think it's a waste. Mayhap so. But what the hell...

God knows how it will stack up against just running on sli'd 980 ti's.

 

[eyetrip]

I expect that it will make no difference, might even make it worse, and you will have wasted a chunk of money...

It wouldn't be the first time I wasted money and won't be the last!



Was thinking it would probably take a 970 to not be a bottleneck, but maybe will prove myself wrong.

Sick as dog with cold so needed something to do something to make me feel better. Spending money usually does that

Run Fluidmark on your 980ti. Then run it on the 960.

Feel a bit silly, get annoyed at the extra heat and noise, remove card and never do it again.

I put a 770 with my Titan Blacks. Big mistake....

Did you test games?

As for best and noise.... Meh. Not like a 960 will be putting out much heat, and it shouldn't be noisy.

Still, you may be right in that I could be utterly useless. If there is any improvement in games, then I will be happy.

As stated though, think a 970 probably would have been a better fit.

I ran heaven no diff whatsoever
I ran firestrike extreme none whatsoever (not even sure if it uses it though?)

with strix970 as dedi physx

what else should i try?

Try some games that support hardware physx - don't think those benches you used do even support it.

Try some batman games or mafia 2... there is a bunch listed here

Well, this experiment may go nowhere quickly, thanks to this stupid bloody z97x g1 mobo.

Doesn't like having gpus arrange in 16x slots 1,3,4. Wants them 1,2/1,2,3/1,2,3,4. And don't know if I care to try changing my loop around to accommodate .

Soon as I have the 960 in slot 4, 2nd 980ti not available! Will have a dig in bios settings, but think my only options are forget about it, or rearrange loop...

God I hate this board...

 

[eyetrip]

Well, I had some time with single 980 Ti using 960 fr physx, and it was a much smoother experience. Benchmark score beat sli Gtx 980 Ti by a little bit

 

[eyetrip]

Pity it doesn't list the minimums.

Hoping I can figure out how to get this 960 whilst still allowing the 2nd 980 Ti to work. Was reading the motherboard manual, and it actually doesn't say you can't have the. As I do.

So not sure why the second 980 Ti becomes unavailable when I plug in the 960. Not even listed in device manager.

Problem for the morning I guess.

It was a driver thing, not a mobo thing, so my bad. Fr some reason it forced only a clean installation fixed it.

Didn't have much time for testing anything today thanks to working a lot.

Did a couple of benches in batman Ak, and the 980 Ti sli + 960 came out on top. Would be even better if sli was scaling better in the game.

For some odd reason though, single 980 Ti with dedi 980 Ti on physx scored worse than single 980 Ti + 960 dedi. tried couple of times. Surely just some driver issue of some sort.

Still, 960 is in and running ok now. It can stay in. Got it running same clocks as my 980 tis for hell of it

Three Nvidia gpu's use too many lanes for a 4790k platform. I was under the impression you could not go with more than 2 Nvidia cards is this wrong then?

My board uses PLX chip, so can have 2 x 16x pcie or up to 4 x 8x pcie.

Just like I was running 3 x 290x previously without issue (apart from crosfire support)
