Friction in newly installed bottom bracket
Sounds like a spacing issue, the cranks shouldn't bind at all.  They may have some resistance with new bearings, but not enough to noticeably feel in most cases. Check that you don't have excess spacers on the spindle and are just using the wavy washer.  

The crank arm bolt should pretty much bottom out on install and the cranks should be easy to turn. (there is a black alloy spacer that is used for BB86 shells included with most SRAM gxp cranks/bb and is not needed on the BB92 install).

If that looks correct, have a visual check in the BB.  It uses a plastic shell and sometimes this can be damaged when pressing in and contact the crank spindle on install.  Next check that the bearing cups are not deformed where they meet the frame on the outside (ie pressed in too hard) which can cause the bearings to run out of alignment, again a plastic shell issue and can happen when using larger headset presses.

Worst case, replace the BB with something like a Wheels Manufacturing or Hope BB that use alloy parts throughout; these are much more reliable for press fit applications as they do not deform like the plastic ones.
