Hey! I'm looking forward to upgrading my VGA and my budget can only handle these cards GTX 560 TI , HD6950 7 HD 7850 because they are nearley the same price in my country N' I've really Checked lots of reviews for these cards but i found that the differences between them weren't similar in each review and of course I Wanna buy the best one from these 3 cards
