Thanks Alex ! yeah I'm dead proud to be building it for her.
She dug her heels in for ages, but, as she's tried later games on her laptop she's begun to realise she really does need a desktop to be a serious PC gamer.
We also bought her a laptop too ! and we got a great deal on it. It's an Asus ROG G73. Has a Sandy I7, 8gb ram, 500gb hdd etc with a GTX 460M which tbh is a desktop GTX 460 so it's no slouch and will easily slice through Sim City, Anna, Alice in Wonderland and the games she wants to play on her laptop. Got it for £500, they were £1800 new.
I know that a modern £700 laptop would be faster but they are £700. They're also not 17" and built like a tank. The Asus one has all of the features of a £1800 laptop tbh, really really nice unit.
That's it there. She also got a Google Nexus 7" lol so she's been really spoiling herself (and me) lately.
