It'll run almost everything on high, if not ultra. Pick up a Cooler Master Hyper 212 EVO aftermarket heatsink - they run for about 35CAD and will let you overclock that i5 to about 4.5GHz. As far as ivy bridge vs sandy bridge: the ivy bridge i5 has better overclocking capabilities because it can handle more heat safely (on the otherhand, it also tends to run hotter).
You can use the same z77 motherboard with an IB i5 3570k and there isn't much difference in price between the two CPUs. However, if you wait for SB prices to drop and you don't plan on OCing... definitely just get the 2500.
I would recommend you to get an ivy bridge CPU core i5 3570K(successor of 2500K). I would also recommend you to go with ATI 7870(as you an go upto 900euro). Hope that helps....!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
