Well what we all have been waiting for since we first saw the introduction of the radeon HD 38500 series has finally hit the public. The driver is out that does it all. Yes CrossFireX, we've wanted it, we've asked for it, and now we've finally got it. This CrossFireX is the next generation of CrossFire technology for Radeon based graphics cards. The latest ATI Catalyst drivers bring us the ability to pair up two Radeon HD 3870 X2's for some quad-GPU CrossFireX action. It is certainly a good action from ATI, and it will also finally shows users the way to triple configs using the CrossFireX technology. Some exciting times ahead and we will see soon enough the answer from the green camp. - TweakTown

ATI Radeon HD 3870 X2 CrossFireX Operation Review

Well, that wasn't as exciting as we had hoped. We're going to start running into CPU limitations again with this kind of setup. We can see this with the small differences being seen between the standard resolutions as well as the lower widescreen. We don't know what we really expected to be honest, but it would have been nice to see something like Crysis get an average of 80 frames. The thing is though, with this issue of small gains for the quad-GPU setup, we don't think it's going to be specific to that of AMD based graphics cards. We guess we are going to see similar issues when NVIDIA jumps on the quad-GPU wagon.

The people who are going to have the most fun with the CrossFireX driver are 3DMark benchmarkers. The rest of the people are probably going to run into the same problems that we had, which involved some applications not running or anti-aliasing not being able to turn on, or just generally very little performance gains. But AMD made a promise that we would have CrossFireX by the end of the first quarter, and good on them for sticking to that promise, but clearly some tweaking needs to be done!
