Nonesense. I'm still using a performant Hackintosh I built 8.5 years ago with a Gigabyte EX58-UD5 board. It's been through several Mac OS upgrades and point updates. The only thing I have to do without is sleep and target disk mode. The trick is to clone your system to a second disk and trial any upgrades on the backup. Usually the only thing required after an upgrade is to re-run MultiBeast. Piece of cake so long as you stick with recommended hardware.
