Two new all-in-one PCs have surfaced from Gateway today, both of which run Windows 7 and use multi-touch capable touchscreen displays. Both the Gateway One ZX6800 and ZX4800 respectively use a 23-inch and 20-inch display with resolutions of 1920 x 1080 and 1,600 x 900.

The ZX6800 runs an Intel Core 2 Quad 2.33GHz CPU with 8GB of RAM, ATI Mobility Radeon HD 4670 1GB graphics, a 1TB hard-drive and 64GB SSD (for apps and OS); there's also WiFi b/g/n, gigabit ethernet, a DVD burner and eSATA port. A hybrid TV tuner and 5.1 surround sound outputs take care of entertainment.

Meanwhile the cheaper ZX4800 uses a Pentium dual core 2.1GHz CPU with 4GB of RAM, Intel GMA X4500HD graphics, a 750GB hard-drive and the same connectivity of its faster sibling. However it doesn't have the SSD or TV tuner options.

Both models are said to become available by late this month/early next with the X6800 carrying an expected price tag of $1,399 U.S. and the X4800 $749 U.S.
