I want to build a gaming pc under 600-700 $ (USD).
Please suggest some good pc parts(Each and every possible hardware)
And the main feature must be that its future proof(no one can predict that but at least run most games maxed including BF3 for next 3 - 4 years)
I cant afford more than that as i am in collage so,you know,still dont earn that much.
You won't be able to run most games at max for 3-4 years with that budget. But don't fret. I would recommend investing in a 2500k processor and decent mobo- that platform will last you that long. As far as GPU horsepower, that will become less powerful (relative to in game performance of newer GPUs) faster.
