Guru3D picked up a new eVGA p55 Classified motherboard and dropped in three of the new Radeon HD5770’s to test out Triple Crossfire (3-way CrossfireX), and published the results for all of us to drool over. Sadly, the effectiveness of the build is throttled by the CPU’s ability to keep up.
Obviously rendering your games with three GPUs equals a lot of brute horsepower, so big that the rest of the PC might become a bottleneck for your graphics solution. That is however a luxury problem though but as an example, Fallout 3 at 8x AA at 1920×1200 performed as well as a 2-way 5770 setup as the processor (Core i7 @ 3.75 GHz) was literally holding back the GPUs from reaching the stratosphere.
