I would get Z97 motherboard with the newer refresh of (lga 1150) haswell cpu's. Ofcourse it'll be maybe 5-10% better then the original cpu's that launched in 2013 June/July.

Z97 if you're willing to OC will potentially allow you to get most of the benefits of Z87; lots of sata 6Gbps, better power & heat stability, support for the m.2 sata standard/pcie sata express. asus & msi have my vote for great looking & performing motherboard from their gaming/oc + workstation grade boards.

I would say that you should get a hold of 8GB ram vs 16 but it's for you to decide.

For the gpu if it's value bang for you buck gaming, either 770/780 from Nvidia or 7970/280X or higher.

From my understanding the 760 FTW cost more then the GTX 770 with the same style of cooler.

Power supply get something with all the right connectors req; single 24pin power, single/or dual 4+4 cpu breakout cable, dual 6+2 pin for GPU, couple sata power. Maybe your power supply if it's a system for high end gaming sli focuses on a 650-800w.

Thank you both for the advice I will take all of it and rethink my system build.
