Rebating = waste of time in my opinion. >_>
eVGA is the best model for 7600GT, in my opinion, as their clocks are a bit higher, and you can OC them just as much as any other 7600GT.
Edit: I've always used eVGAs and XFX when buying nVidia, and they always run perfect for me. BFG is also a nice brand. I have found nothing wrong with my other eVGAs, and my roommate runs two eVGA 7600GTs in SLI with two moniters on DVI perfectly.
