Excluding a case, because this is personal preference. Someone else might have a better build for that amount though, I'd search around the forums and see. alot of people ask for 500 dollar builds, so you might be able to find something better for the price rather than my quick throw together! :) Hope this helps.
The Nvidia GTX 750 and 750 TI cards are better than that card, and they have very low power consumption. The AMD Radeon R7 265 is also a nice upgrade which is better than the 750 series cards, but uses more power. The GTX 760 is a low power card, has great performance but has a higher price. It all your choice!
 


After looking further into it, the furthest you can upgrade is to a Core2 Extreme X6800. This CPU is almost 10 years old now, just like your E6400.

If you're wanting to spend much money, then a cheaper AMD build/Pentium build would serve as a huge upgrade.
 


ok could you please build a 500 euro 548 dollar amd or pentium rig on pcpartpicker.com
