HP Pro 3305 Microtower PC

^[1] This system requires a separately purchased 64-bit operating system and 64-bit software products to take advantage of the 64-bit processing capabilities of the AMD 64 processor. Given the wide range of software applications available, performance of a system including a 64-bit operating system will vary. Dual/Quad/Triple Core is designed to improve performance of multithreaded software products and hardware-aware multitasking operating systems and may require appropriate operating system software for full benefit. Not all customers or software applications will necessarily benefit from use of this technology. This PC does not support the AMD over-clocking feature. AMD’s numbering is not a measurement of clock speed. ^[2] Sold separately or as an optional feature. Availability varies by region.
