The Intel Q6600 was a popular processor for a long stretch of time; there are several good motherboards it's compatible with.
The Intel Q6600 is a Core 2 quad core processor released in early 2007, and it is compatible with the Intel P35 (standard) and X38 (extreme) chipsets, as well as several chipsets from NVIDIA. Each of these chip sets can be thought of as the 'bare bones' of a motherboard, manufacturers then add components like additional PCIe slots and SATA controllers. The Q6600 was a high-performance popular chip, but became standard, as Intel released newer and more capable CPUs.
MSI P6N Platinum
The MSI p6N platinum uses the Socket 775 compatible NVIDIA 650i chipset; NVIDIA's chipset makes some changes from both the Intel P35 and X38 chipsets, in the name of greater performance on synthetic benchmarks. The MSI P6N has two Parallel IDE controllers for old hard drives, and four SATA drive ports for modern hard drives. It has a FireWire port, and an eSATA port for connecting to higher performance external hard drives. It can handle four DIMM slots, each with a maximum of 4 GB of DDR2 RAM, and has two PCI-e slots for graphics, a mini PCI-e slot and three straight PCI slots for older component cards.
Asus Maximus Formula SE X38
Asus built its SE X38 motherboard as a high-end overclocking board for this processor; it has support for DDR2 RAM and is a Socket 775 motherboard working from the Intel X38 chipset. It has several features geared towards the enthusiast market, including "stoplight" color-coded LEDs for showing the voltage going to specific components, and an extensive array of heat sinks going over specific components. It has four DIMM sockets and can take up to 16 GB total; the sockets are color coded for the order you put the DIMMs in for Dual Channel insertion. The motherboard has eight USB ports, one eSATA port and dual PCI-e 16 ports for dual video card usage. It lacks legacy IDE controllers and has six SATA ports for connecting hard drives.
Gigabyte P35-DS3R
Unlike the other boards shown here, the Gigabyte model is geared more towards system stability rather than grabbing maximum performance out of the CPU. While it has four DIMM sockets able to do Dual Channel DDR2 RAM, the maximum ram each slot can take is 2 GB, rather than 4. It has eight SATA2 connectors (offering a performance boost over SATA1), while retaining a lone IDE connector for old hard drives. It has three PCI slots for legacy cards, three PCI-e slots for more modern expansion cards, and a lone PCI-e-S slot for a graphics card.
