Neither...Go to best buy, you will have better luck there if you are looking to just buy. I think you could go wiht just an HP or ASUS desktop. Make sure it has at least an 8000 series Graphics card (Nvidia) Or An HD 4000 series for ATI good luck. You also want at least an intel core 2 duo, for games like prototype and Dragon age Origins. I'm running a quad core 2.66 (OCd to well..3.2-4.0) and 2GB of RAM and also a 9600 GSO 512 OCd by about 100mhz. Good luck to you, Newegg.com has a bunch of resources to teach you.
