Notes
Though we've been able to spend a few days with a Core i9-7900X, getting hold of supporting X299 motherboards hasn't been entirely easy. A variety of boards were on show at Computex 2017, but an accelerated launch schedule appears to have caught manufacturers off guard. Review samples are being held back while software wrinkles are ironed out, and our test motherboard received a major BIOS update just days ago. Please note that neither the CPU nor motherboard were sourced from Intel.
