Hey its my first time posting as well as first time building my own gaming PC.

The components I anticipate to have are:

CPU: i5-2500k

------------------------------
Debating 2500k vs 3570k, and z77-d3h vs z77x-ud3h. Missing a SSD, CPU cooler
Still worried about prices (debating between retailers, shipping, tax, efficiency)

Largest problem is trying to maintain sub $700

Thanks any advice would help

 

[AMD Radeon]

3570K to go, similar price and more efficient architecture...

I was debating between those two since they overclock rather the same amount, but temperature wise is a bit different. Is there anyway I can adjust my build to lower the price? :/
