After demonstrating P67's ability to keep up with X58 in single-, dual-, and triple-card configurations (with the help of Nvidia's NF200 switch), we're pretty much "over" the idea of paying a premium for X58-based platforms. However, there will always be a market for the best of the best, regardless of how much it costs.
To that end, Gigabyte sent us its huge G1.Assassin motherboard to show off the board's unique features, not the least of which is its ability to host four dual-slot Radeon graphics cards in a CrossFire configuration (or three GeForce cards in three-way SLI). Up until now, this editor hadn’t had any experience with the XL-ATX form factor and its extra-large proportions. So, we invite you to see exactly what we saw when putting together a massive dream machine.
There aren't any benchmarks this time around. We planned a review of this beast in a configuration it'd actually be used for: with a quartet of graphics cards in four-way CrossFire. Unfortunately, the Radeon HD 5870s we were using simply wouldn't run stably in that arrangement. So, we swapped in three Radeon HD 6950s, which worked fine. The problem is that we'd still recommend a P67- or Z68-based config for three GPUs. The only way this was going to go down was with four cards. As we dig around for a fourth 6950, we thought we'd present you with this unique build as it stands (imposingly) today.
