thats not called an original game man - original games are those in boxes with booklets worth 1,000 to up 10,000 Rs. - dont call your game originals you are selling pirate copys big diff - your games wont run on systems not modified ok
And sure the 10400F is a good buy, performance is near identical. But the K model is OC'able for some extra juice. Not sure if that worth anything to anyone.
