I had touched on this before, but gaming PC's are often favoured by photographers due to the high spec and quality components. I use a company called OCUK, I have used them for many years buying component to self build. But they have fully built systems. This is a quality company with quality product. Just to give you an idea you can get a system with a 4ghz processor, 16gb ram, and 2gb graphic card, 2 year warranty. For just over £400. All systems are upgradable and customisable.
