Sapphire went a bit overboard with this year's WCG event in Seattle. Over 600 systems are running AMD Athlon 64 X2 processors, Kingston DDR2-1066 memory and Sapphire 670V motherboards in combination with Atlantis HD 2600XT boards.

But the most interesting things are being shown over at Sapphire's booth. The company is showing an engineering sample of its RD790 motherboard combined with three Sapphire Atlantis HD 2900XT cards.

What makes this setup interesting is that these three cards are not connected in TriFire, yet all three GPUs are working together. This is thanks to the bandwidth available with PCIe 2.0, since the 16 lanes are efficiently doubled up. Whether future cards will come with bridges or will they become thing of the past, it remains to be seen.
