I'm looking to purchase a gaming PC. My employer offers a program where they will buy me a computer and I just have to pay for it over a year; unfortunately, they only go through Dell. I've been looking at Dell gaming computers, but I really do not know what to do get. Do I need a specific processor to power a higher end graphics card? How do I determine if the card will power the monitor? How much RAM do I need? HD? I know, I'm a noob, but you're assistance will be greatly appreciated!
