hello,
am building a extreme rig with quad 7970's,i7 3960x and asus rampage 4 extreme....now for physx i want to install an additional card..
i was planning on using the physx card on the middle pcie slot(grey 16x,working as 8x) on the motherboard....but after installing the 4 7970's with ek waterblock's,will there be enough space to install a physx card in the middle slot?
i know a weak card can handle physx smoothly but i didnt want to use a really low quality card...i chose this as its low profile+waterblock is attached///

http://www.newegg.com/Product/Product.aspx?Item=N82E16814130757

would i be able to install it on the middle slot?
is the waterblock attached to the card to thick and should i buy this card without waterblock and use seperate ek block so that its thinner or something else?
and if the card is too thick even after installing another waterblock,
would i be able to use this in the middlec pcie slot??

Couple problems: 1. all that won't fit (unless blocked), 2. CF + PhysX isn't supported short of a (hacked) driver which are typically old. Also, a GTX 580 is CrAzy for a PhysX -- way way overkill.

My recommendation is 4-WAY SLI GTX 680's 4GB versions, PCIe 3.0 (mod) and though I know 4-WAY + PhysX is possible I'm just not certain on the R4E. The GeForce GT 640 can work as a PhysX.

The only reason for this setup is 3xHD+ (5760+x1080).

I did the following for David Truby (done on an SR-2):

I run 3D Vision and even if the HD 7970's were a tad faster and I could hack my way through it I wouldn't mix AMD+ nVidia -- not any more.

Therefore, IMO you need to make a choice of one or the other.

I have nothing at all against the new AMD 7000 series GPU's, and I've built many systems using the HD 7970 -- it's a great GPU. Frankly, I'm pissed nVidia didn't offer >2GB i.e. 3GB or 4GB standard/reference GTX 680. What they should have done IMO is GTX 670 2GB reference and GTX 4GB reference. For enthusiasts this has been a PITA and nVidia aggravated many folks -- well at least the extreme enthusiasts.

What you can run is HD3D + Eyefinity (AMD Eyefinity 3D) until recently you couldn't and 3D Vision was the only choice.

Hey I do NOT want to be the one who pushed you into a 2GB GTX 680, and let me tell you now today (5900x1080/bezel) WILL vRAM bottleneck in some games with highest details + high AA e.g. BF3.

Suggestion - The rumor mill has it that EVGA will be releasing a 4GB GTX 680 HYDRO COPPER CLASSIFIED (soon ~couple weeks) - http://www.evga.com/articles/00669/#GTX680HydroCopper

the 580 wouldnt fit as with the wb attached as it takes 1.5 slots....
there is one slot spacing between each gpu slot on the asus r4e and two slot spacing between the 2nd and 3rd red gpu slots......so the 1st gpu and the 2nd gpu will have 1 slot space..then the 2nd gpu and the physx gpu wont have space between them after installing the physx card/...the same thing will happen to the 3rd card..it wont have space between the physx card....the 3rd and 4th card wont have space between them either because of a pcie sound card that am gonna install....as am heavily watercooling....would the space between the gpu's lay a heavy impact on the performance?

Hello mister 7970s + physix mod guy

Yes this setup is possible but u got to change board to SR-2 or SR-X board

Im not sure about the black x8 on R4E as physix

I would've suggested 2x7990s + 640gtx but the 7990s has no release i think

But yah ur setup is killer if the R4E black slot supports physix and use a 640, 240,440 gt/gtx not a 580/680

thx

The Cheaper rout will be 3 x 680 or 4 x 670 either sli all and add the physx option or SLI 1 less and dedicate 1 to phsx you will be much happier than the frankinstein you are trying to make and it will just work... I guess it is obvious money is not an issue here but the amount of heat you will have in your room from 5 video cards will make you need dedicated AC for your gaming room and I am not even kidding. I have 3 gaming computers in my office and it gets to 82 F in my office after a few hours of play..

@joedjnpc

are you kidding me?lol..you really should check out the asus r4e...

@peanut_316

a 580 might support the middle slot....am 80% sure with the 580 ftw hydro copper 2..not so sure about the 580 ultra classified as its wb is thicker..and it wont support the 680 hydrocopper as the evga 680 hydrocopper isn't a single slot card....

@Thently

am building a loop with a lot of rads...so hopefully heat wont be the prob....and the frankenstein is not only gonna work but also kick some ass.....well all sli/xfire builds have some bad sides..they literally suck at some games...and my room is ac'd
