thanks Pellepel...as for the backplate crushing components, i haven't seen a single instance of this in any forums yet. i was almost positive this would creep up when i first got this board but apparently the standard backplate that so many use for blocks/heat sinks (like the one for the Ultra-120 int he pics) doesn't cause a problem. the EVGA forums is full of people whining about issues with their boards but not one has said anything about crushed components back there...perhaps they aren't seeing them and that is the source to some of their problems, but not likely.
if you are thinking of jumping into the 790i you definitely want to have a stroll through the EVGA forums as well as maybe XFX if it exists to see what you are getting into. a lot of it is user error and newer OC'rs not knowing what they are doing but there are definitely some issues with this board. i admittedly only bench with the board, but there are some quirks with FSB and voltages that i tried to explain here. SLI has never been a problem for me and with enough work on GTL and FSB voltage, gaming at higher FSBs isn't an issue either. those seem to be the major problems people are having from what i see. with that said, my benching consists of stability testing with games, Prime, OCCT, HCI memtest, and all kinds of SPi and 3DMark work for memory reviews and what not, so it sees pretty close to a regular 24/7 rigs type of work. HTH
voltages for all the SPi SS are there in the monitoring software or a small text file that is open in the SS. the 3D benches there isn't but they are going to be about the same at the various FSBs.
GTLs aren't documented and i couldn't list them all but for the most part i have been really simple with them. -80/-80 up to about 500FSB+/-, -110/-110 up to 550FSB+/-, and -155/-155 above 550FSB. for 24/7 stability, that is a different story and going over to the + side has provided some success for stabilizing COD4 around 450FSB.
apparently the pencil vDROOP doesn't work or is hit & miss at best. have a look here...

the thread is getting long and old so maybe start at the back with the newer information. but my guess is that the resistance gets lowered so much that doing it with a pencil is all but impossible because we are lowering the resistance with the VRs to almost zero...which the pencil just can't do, and definitely not with any kind of precision. i actually advise against the pencil mod because you would surely lower resistance to 0 in order to get the vDROOP eliminated and that just can't be good...but i don't really know for sure so take my opinion, and that is all it is, for what it is worth. i am a lazy cat and still haven't taken disconnected the vDROPP VR on my board to find out what it is actually set at to eliminate vDROOP. maybe this week will be the week
