pc in question is the sabertooth in sig below.

case cooling is accomplished by two phantek ph-f140hp's intake and one ph-f140hp exhaust, h100i is push/pull using four corsair high performance sp120's.

msi kombuster 3.3.0 running gpu core burner v2 (furry donut) sli for one hour records the max temp for gpu1 @ 88 deg c, gpu2 @ 76 deg c.

in game i've never noticed gpu1 over 80 deg c (gpu2 lags 10 to 12 deg c behind).

the sabertooth pcie layout is:
x1 #1 - creative zxr (top of mb)
x16 #1 - 780 ti (gpu #1)
x1 #2 - empty
x16 #2 - 780 ti (gpu #2)
x1 #3 - empty (but covered by video card)
x16 #3 - empty (bottom of mb)

i would like to free up space around gpu #1 by moving the zxr to the bottom x16 slot (#3). the question is does populating the 3rd x16 slot with a sound card lower the other two to x4 (they currently run at 3.0 x8)?

thanks for any help!

From what I get from the manual, the first and second slots run at X8, the third will run at X4.
