The Speed of any Computer is dictated by the BUS Speed, which is the TRUE Speed of any Computer. Bus Speed is the Speed in which all components communicate with each other (CPU, Graphics, Motherboard, HD)...
You can have a 4 GHz Processor with a 400 MHz bus and that's all you get....
or you can have a 2 GHz Processor with an 800 MHz bus which is way better...
New computers with Dual Core CPU's that have a 800 MHz FSB (Front Side Bus) are way better equipped to handle such demanding Gaming Apps. Now that said, you need a capable Graphics card as well (with 256 or 512 RAM), and at least 2 Gigs of RAM on the machine.
As To PC or Console Gaming.... I rather sit in front of my 57" HD screen and play Forza than a 20" computer screen.....
