Already done. I was pleasantly surprised that MSI updated the bios to accommodate the 1100T so I didn't hesitate to upgrade the CPU. I'm wondering about the CPU being hobbled in any way by the motherboard even with the bios update.
Well, as long as it works, then you should be able to get excellent performance out of it. The older motherboard might hold the CPU back slightly but it won't be by much (probably less than 5%). Unless you are planning to spend a lot of money for a very small increase in performance, it's not worth it to upgrade the motherboard and RAM to one that uses DDR3.
