After owning an AMD 7850 for a year, which performs quite well, I have decided it is time for an upgrade. I am looking into getting into more advanced 3D modeling and video production, of which most programs don't play well with AMD cards. I have decided upon a GTX 770 w/ 4GB of memory, but am having a few questions about the available models.
Right now, I am looking at the EVGA model with the ACX cooler, but there seems to be multiple models available with no documented differences:
Is there any important differences between these models other than the base clock speed (which I would likely be able to overclock to match anyway) that would warrant spending an extra $25 on?
Also, if you have had any experience with these cards, and advice?
