If you are going to buy a computer, regardless of if it's from the store or built, I would mainly focus on learning more about the ability to upgrade it and on trying to get the most for your money. That includes graphic card, media applications, and definitely the warranty that comes with the computer.  If you had $5000 to spend on a computer I would try to stretch the money as if I only had $1000 to spend.  I would also ask myself how long am I expecting the computer to last and are there any future purposes for the computer other than graphic design. Definitely see and ask around about the new computers and processors that are coming out soon. Knowing when the new computers are coming out will lower the prices of computers that were top of the line in previous months.  You can often bargain for a lower price if you are paying in cash.
