I am new to DIY computer building. I have chosen the XFX nForce 680i LT mobo and the Q6600 CPU. my question is the Mobo FSB speed is 1333MHz and the CPU FSB speed is 1066MHz...is this a problem?

680i boards support both 1066 and 1333mhz FSB.

Hi there,

A little further explanation, to add to Titan's correct answer. A FSB rating on the motherboard will give you the highest compatible result available, so pretty much everything below that will be compatible as well. Of course, there may be some that won't work, so make sure you double-check (explained below). For example, an old Pentium 4 with an 800MHz FSB will also work in that motherboard.

The same rationale can be found with RAM, also. The XFX motherboard you are looking at supports DDR2 memory up to 800MHz. You would be able to install 667MHz DDR2 memory with no problems.

The easiest way to check is to navigate your web browser to the manufacturer's webpage for the component. In your case, this link takes you to the specifications of the motherboard, where we find this information:

Supported CPUs
Intel Core 2 Extreme (dual and quad core), Core 2 Duo, Core 2 Quad, Celeron D, Pentium 4, Pentium 4, Pentium D 9XX, Pentium D 8XX

As your Q6600 is a Core 2 Quad, you can see this is supported.

Cheers
