3 Different Builds 1100 euro

Hi all, this is the first system I'm building myself.

APPROXIMATE PURCHASE DATE:
I would like to start building around 21 November ( My birthday! =) ).

BUDGET RANGE:
Around 1100 Euro = 1650 CHF = 1650 $

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT:
Gaming ( It's the only thing that matters ).

PARTS NOT REQUIRED:
Mouse.

PREFERRED WEBSITE(S) FOR PARTS:
www.digitec.ch, or any other Swiss or Dutch website. (Digitec is in English so don't be scared to have a look).

PARTS PREFERENCES:
None really.

COUNTRY OF ORIGIN:
Switzerland and The Netherlands. (Expat living in Switzerland).

OVERCLOCKING:
I might try in the far future, I won't be a really serious overclocker though. I will start with stock cooling and won't overclock.

SLI OR CROSSFIRE:
Yes in future.

MONITOR RESOLUTION:
As high as it can be as long its within 200,- euro's ( 300 swiss francs ). And the max size is about 23 inch. I found a monitor with 1080 x 1920.

ADDITIONAL COMMENTS:
I will probably add a 5850 ati when the price drops. So after about a year I suppose. And I want to be able to upgrade this system for about 3 years without major changes.
By the way, I live in Switzerland as you might have noticed. And I can purchase without tax so that's 7.6% less.
1 CHF = 0.65 euro = 1 $

So the question:
Which one would be best for my situation? Do you think I should change some of the standard components? Please Comment! =). Are there other better solution for gaming ( while still staying in price range ). Are there ways of lowering the total price?

Best regards, GreenPiggy.
Looking forward to your reactions! Thx and have a nice day!

go for the second build.

Hmm ok thx. But won't it have better gaming results than the i5 750? Or is it the worst gaming machine + highest price? Or just a
too high price for the quality but still a better gaming machine than i5 750?

Thank you very much.
At least I now know the 860 isn't an option =). Now there is only the old fashioned Intel vs Amd discussion. Hmmm oh well I still got some time.

Maybe just a simple question in case I might overclock:
Which one is easier to overclock the AMD X4 955 or the intel i5 750?

Thx again!
