Desktop computer hardware assembly specifications

Desktop computer hardware assembly specifications to create a computer that is intended to use graphics editor, 3D, animation, video, etc.. Although basically a desktop computer assembly specification typically used for gaming in general. As for the task - the task of editing before it is better to use a computer workstation. Unfortunately the price for a computer workstasion still relatively expensive, and can not be assembled as easily as a desktop computer. To get around this I tried to make the specifications of the computer that is optimized for the editing task, at least close to, and not disappointing to use. For gaming, can continue to operate while not a priority and better than a computer workstation. In addition, price to be paid can also be arranged flexibly and affordably.
The qualifications for Desktop computer hardware assembly specifications as a minimum:

• Multicore Processor and 64-bit architecture
• at least 2 GB RAM DDR2 / DDR3
• VGA with a minimum of 256 MB memory buswidth 128 bits, there are technology CUDA (nvidia) / stream (ATI) which allows the processor and VGA work together in parallel in the running software
• The capacity of at least 500 GB hard drive with SATA interface
• Optical Drive DVD RW
• True Power Power Supply for computers that use Core 4 processor with 125 Watt TDP
• LCD Monitor 17 "non wide screen

Something to consider in selecting the specification of a PC computer

Something to consider in selecting the specification of a PC computer:
Power Supply:Who seek to use your good PSU (pure power). Do not be tempted by the amount of watts is proposing. Remember: the price is never bo'ong! If there is who sells the following case PSUnya Sharga 400 rb ² iming with its 450 W PSU (for example), forget it. PSU of this type who just wrote ditulisan 450W, 250W power actually bs you just have interchangeable bruntung. Unless the company was about to assemble low-end motherboard with VGA OB and not much additional component, never use a cheap power supply built-chasing.
