I presently have a rampage 11 extreme, 975 extreme processor o/c 4.35, sector seven ram 3x4 12 gig o/c 1814, 1000 p.s s/c gtx680, ssd drives that I use for x-plane10. Wondering if it's worth upgrading motherboard to sabertooth x79 processor 3930 or 3970 and 2000 speed quad channel ram. Would there be any real improvement over what I already have for running X-plane10 or fsx.
More aboutsystem worth upgrade
Not really since that is a massive rig you got but it is your money.
The only real improvement would be a better graphics card... yours is good but could be better...
