you should go with 3570k and a better gpu. The reason not to go i7 or the i5 4670k ( the haswell ) is cause the haswells are worse at oc than the ivy bridges. For example with the i5 3570k and an aftermarket cpu cooler example : 212 evo (cheap and good quality cooler ) u can oc to 4.5 easily. So if i were u i would go for the 3570k or the i7 one but ivy bridge and get a better gpu.
