Over a month ago I bought the EVGA GTX 670 FTW Signature 2 at my local Tiger Direct retail store. A few weeks ago I tried to return it when Nvidia released their new gpus, but Tiger Direct told me that $118 would be deducted from the refund because of the 15% restocking fee and the charge of the free Metro game ($50 value). My question is should I use the EVGA Step Up program to get the GTX 770 or wait for the new AMD GPUs?
