So my son bought a new rig and gave me back my EVGA 460 cards he had in SLI. So I thought I would use one as a dedicated Phys-X card along with my two 760's in SLI. This was no easy task.
 
1) Physical location of the cards all being double slot occupiers posed a problem on the Dark. I tried the top slot a 760; next available the 460; then the other 760 with long flexible SLI connectors. This resulted in crashing of the system (Windows 10 Pro BTW) whenever the SLI was enabled. scrapped that idea.
2) Placed a 760 in the top slot; followed by the 2nd 760; then the 460. Default nVidia drivers crashed. Got the latest Win 10 drivers and at least they installed. Still could not get SLI and dedicated Phys-x without Windows 10 freezing when I clicked OK in the control panel applet. Now I'm gett a bit pissed.
3) Pulled the 460 and set SLI for the 760's in the upper two slots. That went fine. Shut down the system and added the 460. I then set it to be dedicated Phys-X card. That also worked . So now it's all operational.
 
Ran the usual benchmarks like Heaven, 3DMark Vantage & 3DMark 11 with scores as high as I ever got but no improvement. This is actually good as these test are not heavy Phys-X processing tests and I wanted to know if my SLI was degraded moving the lower card to what I think is an 8X slot and not a 16X slot. 
 
So then I found a Phys_X benchmark and demo by Geeks3D called Fluid Mark. I ran the default full screen test and this was my base result.
Score was 4129, 68 FPS @ 1920X1080. I don't know if that is Good, Bad or Ugly as I have never seen any other results from other setups. If you can post what you know about Fluid Mark, that would be helpful. If you know a better physical setup for my cards that too would be helpful. It also reports my system a Win 8 even though it's Win 10.
 
Thanks!

Here's my results.  Obviously a higher score due to the different hardware used.
 

You're welcome...
 
I think it's more a matter of how tall the case is and/or how high the board is situated in the case.  My HafX is a bottom mount PSU also, but plenty of room between it and the mobo.
 
That is strange about the 44 multi.  I have used that here & there but it didn't change what my PCIe speed was set at.

Very nice OC...  I commented in your new thread as well.  Nice job!

Yep, that looks like it'll do the job...
 
Heck of a nice price on it to I'd say.

Looks like a nice case.  Ought to serve you well.  I like that optional tilting fan behind the drive bays.  Nice idea.
 
If I could add one option to it, it would have a side case fan for blowing air right at the GPU's.  But it looks like you can get plenty of air moving front to back and out the top.  Great choice, great price...

Side note: I don't recall this exactly, but I thought there was a driver issue trying to run either Maxwell or Kepler with a Fermi card?  My memory is sketchy on this though.
 

 
bdary, it was actually Maxwell cards not playing well with Kepler or Fermi for PhysX cards.  Kepler and Fermi are fine together, however as for actual performance differences, a low end Kepler like a 640 will outperform a 570 as a PhysX card and be about even on PhysX performance with a 580.
 
 
Before someone jumps in and says no need at all for PhysX, anymore it is not as useful as it used to be, but there are still instances where it is noticeable, and if anyone has questions or comments on that I can definitely go into it with them.

I knew it was something like.  Thanks for clearing that up Dave...
 
I was really thinking the early driver support was for 600 series on up for Win10, but as I mentioned, my memory was sketchy on that...

Thanks Dave, we can always count on you for great advice. The Dark you sent me last year is still running strong.
 
Thanks again.

Funny you mention that Dave, as I was shopping for a 6 core last night and found the X99 2011-v3 is $100 bucks less than the X79 2011. Prices for the X79 CPU's have not really budged in the past 12 months, I don't get it? You would think with X99 out, pricing would fall. 

That's a really nice looking case, especially for $85 or so. I'm considering building a PC for a family member, and don't want to spend more than $100 on a case, but needs to be full tower ATX. How would you rate it in terms of ease of build?

It's one of the easiest as far as plenty of room and easy to hide the cables. The only negative thing was the instruction book was just some simple words and pictures, no real instructions. It was easy to figure on my own. It's very Modular so you can remove things you don't need. I am very glad I purchased it. I am getting the touch screen fan control and temp monitor next. It fits in the spare 5 1/4" bay and looks cool.
 

 

bdary Have you by chance unplugged those two fans on top just to see what difference in temps there is if you're only using a push setup vs push/pull?  Just curious what the temp difference would be.  With you running such a high OC, it's probably needed though...

 
Funny you should mention that as I pulled them off this morning before leaving for work. So far with normal use I do not see a difference. I did observe while my daughter played YouTube videos,  the system stayed most at 12X and briefly jumps to 15x, so not a real test. Will see what it does with Intel Burn test.
 
So it survived with maybe 1 degree higher at 39X125.
 

 
Here is a shot of the rear LED lamp.
 
 
 

I typically run P/P for 2 reasons.  1)  when under heavy load I can get it cooler than way, and 2) because I run fan controllers and getting more fans at a 1000-1200RPM range is quieter than less fans at 15400RPM to maintain the same temps.
My controller of choice is the Lamptron FC5v2, the v3 has more features and looks nicer, but the v2 is EXTREMELY resilient for heavy load and keeps the voltage more stable to keep the fans at a constant rate.

Yeah the v2 is around 60$ give or take, but I am also pulling close to 2 amps per channel, so I needed something hefty.  I personally never cared for the style of those touch controllers, too flashy for me.  But glad you got something, hope it works well, get us some pics when all is said and done.

Looks good bud...

Sweet build, the only thing missing is some sleeved cables :) 

Thanks catracho4lf. Can I just add sleeving or do I need to replace them? Was think of buying better cables from Thermaltake since it's a modular PS.
