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.
