Hot on the heels of Adobe Creative Suite 5, custom computer maker MainGear has launched its new Quantum Shift workstation PC for professionals. Starting at $3,399, the system is equipped with an Intel Core i7-960 processor, an Nvidia GeForce GTX 480 GPU with 1.5GB of VRAM, 6GB of DDR3 1600MHz RAM, 750GB of storage, a DVD burner, a 1KW modular PSU, maintenance-free liquid cooling, and Windows 7 Professional x64.

With an entry price well over three grand, you know adding components will get out of hand – and fast. That said, many additional hardware options are available, including an i7-980X Extreme Edition CPU, two and three-way SLI configurations up to dual Quadro FX5800s ($7,701), as much as 24GB of RAM ($1,785), up to six mechanical or solid-state storage drives, a Blu-ray burner, a 1.5KW PSU and more.

Additionally, there's a pricier Intel Xeon-based Quantum Shift available, which starts at $3,995 and climbs up to and beyond 20 grand. It can be maxed out with two Xeon X5680 processors, 96GB of RAM, and most of the above-mentioned hardware. Both ship with lifetime labor and phone support and are available right now with an estimated ship date of May 3.
