Thanks for the link to the step-up program, I've been looking for it. Make sure to read the terms and conditions, you have to return your current card before they send you the new one. So keep in mind you'll be without your sweet 6800GT for up to two weeks (that seems reasonable to account for shipping delays and processing). Probably not a deal breaker for most, but something to keep in mind, make sure you have a back-up video card for that time. If you plan on stepping-up I probably wouldn't overclock either...but that's probably just my extreme paranoia talking...
I'm in on an eVGA. Not sure if I'm going to step-up or not, but having the option is great. Ordered yesterday morning and was already on it's way yesterday afternoon.
