PC maker Acer is introducing new M- and X-series desktops and a new 23-inch touchscreen monitor.

The new desktops in the M Series feature Intel Core i3 or AMD Athlon II X4 quad-core processors. It can support up to 6 TGB of RAM, super multi DVD drives, and 1TB hard drives as well. Some configurations will include a discrete graphics card and the systems come with 12 USB 2.0 ports. Pricing begins at $499.99.

The X-series desktops are smaller than that traditional PC tower. They run on Intel Dual Core or AMD Athlon II X4 processors and 4GB of RAM. There is an open PCI-E ×1 and ×16 slot and either 512 or 1TB hard drives. The desktops feature six USB 2.0 ports and are priced at $398.

The new Acer T231H touchscreen monitor integrates Microsoft’s Touch Pack. The company said that the feature would bring Windows 7’s touch-based interface to the ergonomic display.

Users can turn pages, rotate images, pinch-to-zoom, play games, and draw and write on the 1,920 by 1,080-pixel resolution screen. It features a 2ms response time, and a 50,000:1 contrast ratio.

Acer America senior business manager for consumer desktops Irene Chan said, "Our newest desktop models and touch screen display provide our customers with leading technology in very practical form factors that can serve as an entertainment centre for the entire household."
