"Although ASRock is generally considered to be a "budget manufacturer", as a division of ASUSTek, they have been quick to release a motherboard that is supportive of ATI CrossFire Technology. While we have yet to see any prominent ASRock motherboards here in the United States that are capable of NVIDIA Scalable Link Interface (SLI), they are presently offering their 775i915P-SATA2 motherboard, which is supportive of ATI's Multi-GPU Technology. Their 775i915P-SATA2 part is surprisingly based off of Intel's 915P (Grantsdale) + ICH-6 Chipset. However, the innovative engineers at ASRock are on the heels of yet another CrossFire-compatible motherboard. This upcoming CrossFire motherboard is going to be dubbed the 775XFIRE-ESATA2. While we have yet to see an official specifications sheet for this Intel LGA-775 motherboard, it will feature SATA2 support and will perhaps be powered by one of ATI's recent Intel RADEON Xpress 200 CrossFire solutions. We will pass along additional information upon retrieving the information, and as a time-frame for the release, ASRock is simply stating that the new model will apparently be coming soon, and if it does feature an ATI Chipset it will likely not wait for the new RD580."
