ok, doing my google conversions (which may or may not be accurate) you have $84 for a graphics card. Why buy a i5 or i7 if you aren't going to spend any money on the graphics card?
If you are using the computer for non-gaming purposes, use the integrated graphics. If you want to use it for gaming, up your graphics budget and decrease your CPU budget.
Anyways, you can probably pick up a 6770 for that much, but I'm guessing since I don't know what the retailers charge where you are, and even if I did it would have to be in English for me to figure anything out.
