Gateway's new GM5664 desktop does Blu-ray and HD DVD, has kid brother that doesn't

Gateway is releasing two new desktops today, both sporting some features we've grown accustomed to, but also introducing some new hotness into the typically stale market. The new models -- the GM5664 and GT5662 -- share a slew of the same features, like the ATI Radeon HD 2400XT graphics card, 3GB of RAM, and 8-channel 7.1 audio, but they also have some notable differences. The GM5664 comes equipped with a Hybrid-SuperMulti optical drive, which gives you the ability to play Blu-ray or HD DVDs to your heart's content, while also handling typical DVD-RW functions. The system is also packed with a 2.3GHz AMD Phenom 9600 CPU, 1TB hard drive array, and an analog / digital TV tuner. The GT5662 includes a 2.2GHz AMD Phenom 9500 CPU, does away with the dual format drive, halves the storage space, and axes the TV tuner. Both are available now for $1,149.99 and $749.99, respectively.
