When Intel's Lynnfield processors show up next month, upgrading from a Core 2 system will involve retiring one's LGA775 cooler or, at the very least, getting new mounting kit. But it doesn't have to be that way. According to OCWorkbench, ASRock's upcoming P55 Deluxe motherboard will have mounting holes for both LGA775 and LGA1156 heatsinks.
ASRock has a reputation for unusual designs, of course, like motherboards with two socket types or support for new CPUs on old chipsets. This design is almost tame by comparison. OCWorkbench's photos show the P55 Deluxe has its LGA1156 mounting holes positioned normally around the socket, while the LGA775 holes are rotated slightly.
The design works, too. OCWorkbench claims it managed to mount "an older LGA775 Gigabyte heatsink" (possibly the 3D Rocket II, which also supports Socket 939 Athlons) on the P55 Deluxe "with ease."
ASRock's website says this motherboard supports CrossFire and SLI multi-GPU setups, and it comes with a PCI Express x1 card that adds 6Gbps Serial ATA ports.
