There's no mention of using a grounding strap. Now alot of people dont bother with these but IMO its always better to use it, especially when they cost a few pounds, compared to having to pay for a new GPU etc.
You mention intel uses a socket 775, but no mention of AMD's latest AM2 socket.
You need to mention that PCI-E x 16 is the best for GPU's
cheers for the edit mattie and yh although i would love to see this stickied it does seem to be getting a little excessive up there so yh the guide idea is prob better
