So, numbers can talk for itself. With the price tag $199(HD 4850) and $299 (HD 4870), RV770 is the BEST bang for the buck. Compare to GTX 260, A $299 only HD 4870 is a smarter choice. Yes, using this kind of word seems quite biased, but if you read all numbers from our review you will see my point.
Compare to GTX 260, HD 4870 is only 3/4 of its price while test items show the card have almost the same firepower!
HD 4850’s rival is 9800GTX, and we can see while their price keeps the same, HD 4850 have more than 15% leading.
