To satisfy my needs and build what I consider the ultimate rig, (which I am building myself), it will be a good $1500=1131.30 Euros. If I were you, I would save up as much as possible. Do not settle for less as in the end you will be unhappy. Save for as long as you possibly can. If you can save up 1000 Euros you can build yourself the ultimate rig and use all of the candy described above at 40fps. You would never have to worry about getting a new rig for years if you spent enough money. Generally, what you spend is what you get. Don't be in a hurry to buy something quick and cheap just because you can, and do plenty of research.
Best of luck
