The iMac "Core i5" 2.8 27-Inch Aluminum (Mid-2010) is powered by a Quad Core 2.8 GHz Intel "Core i5" I5-760 (Lynnfield) processor with a dedicated 256k level 2 cache for each core and an 8 MB shared level 3 cache. In lieu of a system bus, it has a "Direct Media Interface" (DMI) that "connects between the processor and chipset" at 2.5 GT/s.
By default, it is configured with 4 GB of RAM (1333 MHz PC3-10600 DDR3 SDRAM), a 1 TB (7200 RPM) hard drive, a vertically-mounted slot-loading DVD±R DL "SuperDrive", and ATI Radeon HD 5750 graphics with 1 GB of dedicated GDDR5 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 an audio capable Mini DisplayPort, which supports an external display up to 30" (2560x1600).
Externally, the "Mid-2010" iMac line uses the same "edge-to-edge" glass design and "seamless all aluminum enclosure" as the "Late 2009" models replaced. Internally, however, the "Mid-2010" line is equipped with faster processors, faster graphics processors, and faster memory, as well as support for the SDXC SD card format.
The "Mid-2010" iMac models include a compact aluminum Apple Wireless Keyboard and a multi-touch "Magic Mouse," but for US$69 could be upgraded to include a multi-touch "Magic Trackpad" that "enables users to scroll smoothly up and down a page with inertial scrolling, pinch to zoom in and out, rotate an image with their fingertips and swipe three fingers to flip through a collection of web pages or photos" just like on Apple notebooks from the same era. An aluminum remote was offered for an additional US$19 as well.

||Core i5 (I5-760)
||This model is powered by a 64-bit Intel Core i5 "Lynnfield" processor with quad cores (four independent processor cores on a single silicon chip). Each core has one thread, for a total of four threads for the system, as well as a dedicated 256k level 2 cache. The processor cores share an 8 MB level 3 cache. It also supports "Turbo Boost" -- which "automatically boosts the processor speed based on workload" (so if an application is only using one of the four cores it will automatically increase the speed of the core in use and turn off the unused cores) -- up to 3.33 GHz when needed. However, it does not support Hyper Threading.

|| Custom Speeds:
||2.93 GHz (Core i7)
||This model additionally could be configured with a 2.93 GHz Quad-Core "Core i7" processor (I7-875K) for an extra US$200.

||X 10.6.3 (10D2322a)
||*This system fully supports the last version of OS X 10.8 "Mountain Lion," OS X 10.9 "Mavericks," and OS X 10.10 "Yosemite" except for Power Nap and AirPlay Mirroring functionality (which also requires an Apple TV 2nd Gen or later). It also supports the last version of OS X 10.11 "El Capitan" -- including Mac-to-Mac AirDrop capability -- but no other advanced features are supported like Metal graphics acceleration. It is capable of running macOS Sierra (10.12) as well, although it does not support the Universal Clipboard, Auto Unlock, or Apple Pay features.
Please note that OS X "Lion" 10.7 and subsequent versions of OS X are not capable of running Mac OS X apps originally written for the PowerPC processor as these operating systems do not support the "Rosetta" environment. To run PowerPC applications on this Mac, it will be necessary to use Mac OS X 10.6 "Snow Leopard".

||*Apple's Boot Camp 4 supports the 32-bit version of Windows 7 on this model and Boot Camp 5 supports the 64-bit versions of Windows 7 and Windows 8. Earlier versions of Windows are not supported.
Although Apple does not support Windows 10 via Boot Camp 5 (officially or otherwise), this system meets Microsoft's hardware requirements and it very well may be possible to boot Windows 10 on this Mac. If you have installed Windows 10 on this system (successfully or unsuccessfully), please share the results of your experiment. Thank you.
