Performance in Simulators
Race Driver: GRID
The Radeon HD 4670 CrossFireX configuration performs well in this test, closing the gap from the GeForce GTX 260 Core 216 to zero as the resolution grows up. Moreover, it is a mere 8% behind the leading Radeon HD 4870 1GB. So, we have to correct our opinion about the usefulness of entry-level multi-GPU solutions, although they only make sense if cost much less than GeForce GTX 260 Core 216 and Radeon HD 4870 1GB cards.
X³: Terran Conflict
The Radeon HD 4670 CrossFireX is only inferior to the Radeon HD 4870 1GB at high resolutions (the gap is a mere 6-8%) and equals the GeForce GTX 260 Core 216 at 1280x1024. The scalability varies from 40 to 60%, which is somewhat lower than in the previous games.
