Lost Planet Extreme Condition Colonies Edition
There is again no data about the cards’ bottom frame rate. As for the average speeds, the Radeon HD 5750 tandem easily competes with the Radeon HD 5870!
S.T.A.L.K.E.R.: Clear Sky
This S.T.A.L.K.E.R. series game is known to scale up well and, like in the previous tests, the two CrossFireX configurations are no slower than the single top-end graphics cards. Take note that there are no slowdowns in this game (I do not use antialiasing because the frame rate is already too low).
Far Cry 2
CrossFireX technology works blamelessly in Far Cry 2. The 90% performance growth relative to the single cards helps the Radeon HD 5770 and 5750 CrossFireX configurations outperform the Radeon HD 5870 and HD 5850 in the low-quality test mode and equal them in the FSAA+AF mode. The bottom frame rate is high enough, so there is no discomfort with the CrossFireX tandems when playing this game. The new Radeon HD 5770 is overall slower than the GeForce GTX 260: a 128-bit memory bus just can’t beat a 448-bit one.
