Word of warning if you try to install a different operating system.

I got a Gateway Quad-Core, and the installed hard drive WOULD NOT allow any operating system other than Vista Home Premium 64-bit. I got a bigger faster drive and was able to install Win Server '08 without any problem.

I'm told that this occurs on some of the newer Gateway models, not sure if it would apply to what you bought. But if you observe some bizarre O.S. behavior or flat-out blue screens of death, it could be what I encountered.
