Yeah the 'new' GTO was truly my love car. Got one brand new right off the boat with 0.25miles on the dash, drove it for a year, then took it apart down to the frame and started customizing it. I worked with several car part companies in Australia to get aftermarket parts developed, and tested out a lot of stuff nobody here stateside had ever seen before. Helped get the Harrop supercharger designed for the car and everything.
I had planned to keep the car for life, even bought spare interior parts, carpet, etc. Never had a chance to finish out my goal though, while driving to work one day a lorry hopped 3 lanes over and ran over the car, throwing me across the highway like a pinball =(
I drive the Commodore now, the Pontiac G8 GT. I got it before they canned it and turned it into a Chevy import (eww..)
Update on the cards: Sure enough it appears my reboot issue on the 5x rig was simply overheating of the cards due to the PSU. It's been stable ever since redirecting the hot PSU air.
