hey guys,
would like to ask for your advice.
i recently bought a new computer , with the relevant parts for my question are :
zalman cnps12x (cpu cooler)
rampage 4 extreme
gigabyte 780gtx.

now - my question -
because of the cooler , i cannot put my graphic card on the 1st slot(its on the 2nd slot).
DOES IT AFFECT ANY (even the minuscule amount) GRAPHIC PERFORMANCE?

if it does , its a shame , my processor is running 4.3ghz on 29 Celsius (idle) and 40 celsius on full all 8 threads 100% .

my case is antec eleven hundred - if you think i should remove my cooler ( :( ) what other cooling solution could i use that will give me somewhat the same results on the heat of the cpu ?

thank you

nVdia disabled PCI-E 3.0 on the Kepler cards for X79, sorry. Lack of PCI-E 3.0 is not an issue until you go into quad monitors\cards and such. Go into the options and disable power saving. Re-seat it in the second red slot and go on GPU-Z and do this Hardware and Sound > Power Options > change plan settings > advance settings > PCI-Express > Link State Power Management and disable such. You can also run the test and the PCI-E link will change on GPU-Z itself, from there you can snap me a a photo.

If you use the second PCI-E 3.0 slot (Red) there will be absolutely no performance loss whatsoever.

thank you for your response , i might of had put this computer together but im kinda at a loss with this
this is a link to the motherboard photo from top.
http://cdn.wccftech.com/wp-content/uploads/2013/04/ROG-Rampage-IV-Extreme.jpg

now , looking from the TOP (area closer to cpu) --> DOWN , there's
pcie_x16_1 ( the one at the top - i cannot put anything there.)
pcie_8x_2a ( THIS IS WHERE MY GTX780 IS AT)
***disregard the black one in between***
pcie_x16/x8_3 ( empty)
pcie_x8_4 (there's a dedicated physix asus gt9800)

is this the right combo ?
should i move the gtx 780 to the one with the " _3 " in it ?

The second slot is a PCI-E 3.0 X16@X16 Slot, there will be no performance loss whatsoever.

Also, the 9800GT for PhysX is unneeded and is perhaps actually bogging the 780 down. The 780 can do PhysX faster on its own than with a 9800GT.

even though it written pcie_8x_2a it means that its pci-e 3.0? (is there anywhere i could check in what pci-e the card reports that its running?)

and thanks - ill be taking that 9800gt tomorrow morning.
(and just asking - my brother has an sli of 470gtx , with a 9800gt for physix. will it bog down his aswell? if so, id be ought to tell him..)

The general rule of PhysX is that if the main card is more than 2x-ish more powerful than the PhysX card, the PhysX card will bog it down sometimes. Go on GPU-Z and check the interface, press the question mark on the side to see the true interface that the card is running and snap me a photo so I can help perhaps.

Ok so i've put it in the third one , the pcie_x16/x8_3 , and now its running on pci-e 2.0 , but x16 :) so its already an improvement on what i had. question is - why doesnt gpu-z show me its pci-e 3..?

Apparently it was only the GTX 6-series that did not support PCI-E 3.0 on the X79 chipset. No problem, don't forget to select a best answer :p Which slot is it in, the second red one?
