I finally got my quad with 4gb ram 500gb hd and the marvellous 7800gtx yesterday. ALL I CAN SAY IS OMG. It is a beast. it is frickin huge. And is so powerful, like i knew it would be, but seriously. My powerbook does the Photoshop radial blur test at 100% and best quality in 2mins 30 secs, the Quad does it in 16secs. It is amazing. Mine wasnt meant to be shipped till 29/12 but i got a call from my grandma that a big box had arrived at her door
