How can i lose money on this build without losing too much performance?

[squizzer]

trying to get my build sub £700 as i am on a tight budget, any recommendations on different parts without losing too much performance. Ideally, I would like to use two monitors via VGA and get high to ultra on games like battlefield 3 (I know it's a big ask!)

Anyway, here are my current plans......

You wont need 16GB of RAM for gaming, 8GB is the maximum you'll need for the considerable future. £50 saving right there. Look for a version of windows 7 or 8 on ebay. You can buy OEM versions of windows 7 for £35. Shop around for the corsair power supply, my 650W CX series only cost me £45, amazon certainly isnt the cheapest place!

Generally just google everything. I know for sure that you can find everything cheaper from different sources that amazon. If you want to save money there are many reputable websites out there.
