The 4770 takes an early lead in 3DMark05, but is soon put in place by the higher frame buffer of the GTX250 when AA is applied. 3DMark 06 is an entirely different story with the 4770 being beaten by both the 9800GTX and GTX250. In Vantage, second place is all the 4770 can muster, but there isn't much in it between the 4770 and the GTX250 when AA is applied.
A mixed bag of results. Perhaps our Gaming Benchmarks will better illustrate the true performance of the 4770.
