Introduction

ATI Radeon HD 5770 in Triple CrossfireX

Most of you guys surely appreciated the release of the all new DX11 class Radeon HD 5770. Some of you might even place two of these cards into CrossfireX multiGPU-mode, and as our reference article has shown, if the game is supported it scales really well.

There is however a small group of end-users who like to go a little more aggressive and well... pimp their PC even more, by adding a third card. We call such people Gurus as you match our demographic really well ;)

Now in the past we on several occasions have warned people that once you pass two GPUs, things tend to get complicated. Often you see more driver issues, unsupported games and well... just plain old silly weird things.

If you pick up three Radeon HD 5770 1024MB cards say at 150 USD, would that bring game performance to an uber high-end level? Well, we wanted to find that out. So we took a new eVGA P55 Classified motherboard which has plenty of PCIe x16 ports, popped in three Radeon HD 5770 1024MB cards and once again ran our test suite of software to see what performance scaling is like, and where we end up anno 2009 with driver issues, as there are bound to be at least a few of them.

Let's check it out shall we?
