TrustedReviews have looked at the Gateway GT5074b
Inside, we find a system built around an Intel Core 2 Duo E6320 processor (which shares 4MB of internal cache between the two cores) supported by 2GB of main memory on a 1066MB front side bus. There's a 320GB SATA hard drive for all your storage needs (even if you regularly record TV programmes to it) and a 256MB nVidia GeForce 7500 LE graphics adapter, which runs cool enough not to need its own fan. In fact this machine runs commendably coolly and hence very quietly.Gateway GT5074b Review
