ok your an idiot or a troll .. those tests are all with high aa and af... 5770 choke on high aa and af, if you put it at 2x aa and or 0 - 2 af.. the 5770 would be running up ALOT higher on frames probably double, find one card in the 5770 price range taht does anywehre near as good.... didnt think so.. not only does it give the most fps per dolalr it also gives the most fps per watt.. its an extremely efficient mid range card.. comparing it to high ends is doomed, ive never been a fan of crossfire, i dont use crossfire, i hear SLI is alot better, but comparing a mid range card to high ends? seriously what did you expect
the 460 does about 33% better than the 5770
it also costs $230 but you can pick up a 5770 for $150-160 230 / 155 = 33% price difference so if u dont have the money to spend on a 460 you wont fins anything better at that price point in DX11
