I do know that this computer has PCI/PCI Express slots, but I don't know specifics... it wasn't printed. I think the major issue for me is the fact that even though changing a graphics card is easy (ive done it many times) the CPU will still be fail. I've decided to do a return of the product the moment it arrives. It is unfortunate that I will lose the shipping cost. But hopefully I will find something in my price range that can do what I want. Its just trying to figure out how sit down and actually take the time to read all that mumbo jumbo and see what is good.... which I hate sifting thru all that stuff... but i guess I ought to :/
