English is not my native lingo so I appologize now for my grammar and spelling.
You won't see that much improvement over the CPU you have now with a FX-4170 upgrade. Are you opposed to moving to Intel? You will get the most 'bang for your buck' (or whatever your currency is ) with an Intel upgrade. The HD 6850 should be fine if you game at 1680x1050 or less. You can get decent frame rates up to 1920x1080 with some reduced settings too. I would recommend a Z77 based motherboard and as much CPU as you can afford. Even the lowly i3-2xxx will be an improvement over the Athlon system you now have and a better upgrade than the FX 4170. But an i5 is better.
