Radeon HD 3870 X2 in Crossfire X Tested - Final Thoughts

The latest ATI Catalyst drivers bring us the ability to pair up two HD 3870 X2s for some Quad-GPU Crossfire X action.

Final Thoughts

 

Well, that wasn't as exciting as I 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 1280 x 1024 and 1920 x 1200.

 

I 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 80FPS.

 

The thing is though, with this issue of small gains for the Quad GPU setup, I don't think it's going to be specific to that of AMD based graphics cards. The chances are we're going to see similar issues when it comes to NVIDIA wanting to jump on the QUAD GPU band wagon.

 

The people who are going to have the most fun with the Crossfire X driver are 3DMark bench markers. The rest of the people are probably going to run into the same problems that we had here, which involved some applications not running (PT Boats) or AA not being able to turn on (Half Life 2 Episode 2), or just generally very little performance gains.

 

AMD made a promise that we would have Crossfire X by the end of the first quarter, and good on them for sticking to that promise, but clearly some tweaking needs to be done!
