You cannot put the money to step up "EVGA bucks cannot be used for the step-up program, EAR, or other exclusive EVGA programs." The eighth one on the list of terms and conditions.
Well, good for EVGA, if they stick with it. I'm staying put, I'm no super techie so this is my way of giving back to the forum that helps me out when I have questions.
