Neosteve that RAM isn't any better. It's way too much money for RAM that runs slower than those G.Skill sticks he has. I just read an article on that exact brand he's getting and it would run at 275MHz DDR550 at 2.5-3-3-7 timings and a lot cheaper than those OCZ.
They have 2.5-4-4-8 on there because that 100% guarantees to run at that, but I wouldn't doubt one bit that they can do it 2.5-3-3-7
Those sticks you posted are no where near worth getting over the G.Skill
