HD 7070 Ghz Matrix edition new from asus
Don't purchase the Asus Matrix - the cooling configuration takes up a whole three slots so if you want to add a second one later on, you'll be SOL. Get the Sapphire or XFX versions instead.
I'd personally lose the expensive peripherals. You don't need to spend $100 on a keyboard and $90 on a mouse, you can always get those things later.
