You could probably find these parts for cheaper by looking around. Try looking for bundles that have the motherboard, CPU and RAM altogether.
This build should max out any game out at the moment on single monitor setups at at least 1080p.
And in the future when it starts getting outdated, that motherboard and PSU will give you the capability of getting a second 6870 to give it some extra power.
Also that board has an 8+1 power phase which makes it safer when overclocking the CPU.
Spend the rest on energy drinks and crisps!
EDIT: Might want to pick some fans as well for the case and cooler. Blue Coolermaster Sickleflow fans would go well with the stock blue fan in the case, or if you prefer you could get green or red ones. They're decent enough fans and look nice
Just saw that it says you are from Serbia as well. Keep in mind that these are prices from a shop in the United States and they may not be the same price in Serbia.Edited by amorph - 4/25/11 at 11:48am
