Hey PBAsydney,
Welcome to T.F.!!
Your picked out parts look good, but there are areas where you can save money, and get better parts.
The motherboard is a great choice, if you want the SLI option, along with other features...but SLI isn't worth it, so I would suggest the infamous Gigabyte P35-DS3R, if it's available in your area....it's futureproof and an overclocking dream.
Don't get the e6700. It's too much when the lower models such as the e6320, e6420, or e6600 can overclock way past the e6700, for less green. You may also want to consider waiting for July 22, in which Intel will slash prices of their C2D line, in addition to launching new CPUs, like the e6750....which is like a perfect combination with the P35-DS3R motherboard.
Don't get the factory overclocked version of that graphic card. Just overclock it yourself, for free.
A lot of people will suggest the G. Skill HZs, for the memory. That's if it's available, wherever you're buying the parts from. Another suggestion is the Crucial Ballistix....but this is only if it's available at store. If not, OCZ will do fine.
Sora will tell you that the OCZ line of PSUs, specifically the GameXStream series, have ripples on their +12v rails. It's not necessarily a bad thing, but it's not good either. So I would suggest, if it's available, a Corsair, SeaSonic, or XClio.
