2 GTX 570s would save money indeed, & probably would have a sufficing performance increase, especially if overclocked but the level of overclocking from stock it could make heating quite an
issue?

I got a issue of PC Format today which is one of the most revered computing magazines in the UK, in this
review of the Ginger6 Define XL it comments that it had made a "baffling CPU decision" where it's used a
2500k for a AMD Radeon HD 6990 which has put down it's gaming & onload performance compared to a computer
with a 2600k & a GTX 590. This is apparently due to having half the threads & the slightly lower overclocking capability.
Though really as a whole a 2500k would save quite a lot of money, just that there is a chance that it
would lower the overall performance too which is the last thing you want if you're getting a computer
with a superb graphics card selection.
EDIT:
Here's some lists from you to choose from, the Z68 lists are for you to choose if you'd like your computer
to run much more smoothly but your games will suffer more for having a single Graphics processing unit.
I've shown some options of 120mm or 140mm, the 120mm I've chosen are more loud & expensive but have
better airflow due to their higher RPM (there's even higher ones for the same price but then the noise may
become a large problem).
It always peaks at around your max budget & even on one list at about 9 euros over but these setups should
be getting the best of what you can get, such as the GTX 590 won't work optimally without a 2600k.
Z68 pack with overclock pack, a single GTX 570 & 120mm fans
Z68 pack with a single GTX 580, non-overclocked & 120mm fans
P67 Pro, GTX 590, Non-OC i7 CPU & 140mm fans
P67 Pro, GTX 590, 2500k OCable, 120mm fans
P67 Pro, x2 GTX 570s, OC pack, 140mm fans.
Also I've forgotten to mention you can't SLI a GTX 590 on 3-way motherboards such as these boards, you'd have to get much more expensive motherboards, instead you could
SLI 3 GTX 580s in the future though, but as many people including me will say there's not much that will use all 3 GPUs at once, not even Sims 3 will use a 2nd GPU for me.
Feel free to pick out a list & edit it or at least say of your intentions for me to make an improved one, such as for the Z68 GTX 580 board you might want a 2600K CPU & one less
fan if you want to in future buy the rest of the OC kit, & ofc your then not restricted from getting an extra 580 in the future either so that you can have a superb computer.
