Yes. I did hear about the cards (any of the three) being an overkill for res less than 1900x. That is why I plan on getting a better monitor in the future. Thanks for the input.
Oh I think I will go with a 6850, the price is normally 250,000-320,000 won (Korea), but I somehow found a 160,000 one lol!!! In fact, I will buy two for crossfire (for future use).
