The 27-Inch iMac (Late 2009) features a 3.06 GHz Intel "Core 2 Duo" processor, with two independent processor "cores" on a single silicon chip, a 3 MB shared level 2 cache, a 1066 MHz system bus, 8 GB of RAM, a 256GB (SSD) solid state hard drive, a vertically-mounted slot-loading DVD-R DL "SuperDrive", and ATI Radeon HD 4670 graphics with 256 MB of dedicated GDDR3 memory.
It also has a built-in iSight video camera and built-in stereo speakers underneath the 27" glossy 16:9 LED-backlit TFT Active Matrix LCD (2560x1440 native) display "with IPS technology".
Connectivity includes four USB 2.0 ports, a Firewire "800" port, built-in AirPort Extreme, and Gigabit Ethernet, as well as a Mini DisplayPort, which supports an external display up to 30" (2560x1600). This model also "supports input from external DisplayPort sources" with adapters, so it can be used as an external display for DisplayPort-equipped devices as well as a computer.
