Yes, FreeBSD can handle it. As usual, Windows is the problem. From what I've read, only Windows 7 64-bit supports GPT, and then only with UEFI. So it's very likely that MBR is the only practical choice. Another trick is that Windows generally only has drivers for what was present when it was installed. So switching the BIOS to AHCI for better performance can result in Windows not booting. It is possible to locate the Windows drivers and install them. Otherwise, FreeBSD will work fine without AHCI, disk IO will be just a bit slower.
