Either one to be honest at that resolution you should be fine. Personally I like the ivy 3570k so I would go with that build. My current res is 1600x900 And with the specs in my sig I max everything out.
At your resolution, the second build would be pretty solid. Specially since you have the i5 3570K. However in terms of gaming, you'd want a better GPU and if you ever upgrade resolution, you'd want the 1st build.
You can check out my $650 build. Not quite quid prices but... it'll be somewhat reflected after a conversion. http://www.squidoo.com/electronicandmore#module14669582...
In your case, a better GPU would be more important. And the AMD FX-6300 is an amazing budget chip that performs better than the i3 3220 and can still overclock. Plus you'll still get that 7870 goodness but save money.
