Do you have any components? Case, monitor, keyboard etc.
Also, its pretty hard to determine performance on games that aren't even released yet
I have a monitor(23" full hd LED), keyboard and a mouse(deathAdder 2013). As for games which are out now something which could run GRID 2, BF3(High settings). I'd rather spend a $100 more if you can add a good GPU. Any help will be appreciated
