I'm looking to upgrade my GPU but I don't have a ton of money to invest in a new one. I've got a Radeon HD 7850 currently and would like something more powerful but I also don't want to spend a fortune on it either. Ideally something in the $300 range would be great and $400+ is too much. I know this kind of question must get asked a lot but when trying to find one myself, I kept finding various GPUs that were the same but from a different manufacurer or would have minor different specs and yet would have vastly different price differences. =\
