If you're considering the latest ROG CG8580 'Tytan' gaming desktop PC, obviously one key purchasing factor is knowing how well it performs in the latest games. It's OK to admit you don't know what a '4.6GHz Core i7-3770K and GeForce GTX 680' equates to, or even if you read a Geforce GTX 680 performance review you'll get a rough idea but the likelihood is that the underlying PC used is different from the Tytan.
