I currently have the SAPPHIRE 100338L Radeon HD 6770. I had just purchased it back in the end of December so it is almost 2 months old. I had just seen that the 7770's had come out. I was wondering I have been looking around online for comparisons between the two but couldn't find too much. I was wondering would it be worth it to try to sell mine and get a 7770? Or would I just be better sticking off with what I have for the money?
