A 2 GHz Pentium class 4 chip is not as fast as a 2 GHz Intel Duo Core processsor. Speed comparisons in terms of the number of megahertz are only valid between chips of the same series. Many of the latest computers are also enabled with twin processing. And another crucial factor is the bus speed. This refers to the speed of data transfer from RAM memory to the CPU the central processing unit . the chip . CPU performance can be restricted by slow system bus speeds so faster is better especially for Photoshop work where large chunks of data are always being processed. the screens directly. The window is north facing so I never have any problems with direct sunlight entering the room and what daylight does enter the office can be controlled with the venetian blind.

The monitor should be level with your line of view or slightly lower. Once you start building an imaging workstation you will soon end up with lots of electrical devices. While these in themselves may not consume a huge amount of power do take precautions against too many power leads trailing off from a single power point. Cathode ray tube monitors are vulnerable to damage from the magnets in an unshielded speaker or the electrical motor in an inkjet printer. Just try not to position any item other than the computer too close to a CRT monitor screen. Interference from other electrical items can cause problems too. To prevent damage or loss of data from a sudden power cut place an uninterruptible power supply unit between your computer and the mains source. These devices will also smooth out any voltage spikes or surges in the electricity supply. Choosing a .
