Review http://www.xbitlabs.com/articles/video/display/catalyst-9-8_5.html#sect2 The new driver speeds both cards up in Company of Heroes: Tales of Valor. The bottom speed of the Radeon HD 4870 X2 grows up by 47% at 1280x1024! The Far Cry 2 results are impressive: the dual-processor Radeon HD 4870 X2 is much faster with Catalyst 9.8 than with Catalyst 9.7. If we suppose that Catalyst 9.7 does not enable CrossFireX mode, the Radeon HD 4870 X2 would be slower than the overclocked Radeon HD 4890, but that’s not so. They have the same average frame rate. Thus, the developer must have corrected some bug in the driver, hence the impressive performance boost. And it is in Far Cry 2 that a 50% boost is actually promised in release notes. Unfortunately, there is no performance growth in the FSAA+AF mode. Amazing results... definitely worth getting!
