MojoKid writes "Historically, all-in-one desktop systems like the iMac, HP's TouchSmart and similar designs that incorporate a full system on the backside of a monitor, haven't offered performance that was competitive to their full-sized desktop counterparts. Part of the reason is that many of these systems are comprised of low power notebook platform PC components inside thin chassis designs with minimal airflow. However, as mobile platforms have become more powerful, so has the all-in-one PC. Dell's recently launched XPS 27 Touch, with Intel's Haswell mobile processor and an NVIDIA GeForce GT 750M on board, is an example of a new breed of AIO hitting the market now. The system is based on a 27-inch panel with 2TB of storage, a 32GB SSD cache drive, 8GB of RAM and performance in the benchmarks that keeps pace with average midrange full-sized desktops. You can even game on the machine with frame rates at the panel's 1080p native resolution with medium to high image quality. It's almost like the all-in-one finally grew up."
