I can buy a Lenovo PC for very cheap, with an i5 2400 in it. That may not seem very good, but I can always upgrade to an i7 2600, and I don't play games that require more than a laptop processor. They do, however, need a good GPU. That's why I want to do this. However, I've read things about OEM motherboards not providing 75 watts through a PCI-E x16 slot like a normal one. That means no matter what PSU I stick inside the computer, a GPU would never work. I want to know if this specific model has that problem: Lenovo ThinkCentre M71e.
