We have to give credit to NVIDIA this time. Rather than having a big paper launch and putting users to wait for months until the actual cards make it to retail, the new GeForce 7800 GTX cards have been made available immediately into retail. Even a few internet stores are selling them already, at the not so friendly price of $600 ;).
Our friends at Newegg and ZipZoomFly also have a few more brands for you to choose from.
