$900~ gaming: 1080p / High settings

A friend of mine is wants to build a gaming rig for around $900. He doesn't care about mining, and doesn't need to do anything but game. He initially played on mine and said he would love something identical, but I talked him into future-proofing a little. (I have an FX6300 and GTX 760) I bought him the NZXT H440 for his birthday, so the case is covered. Here's what I came up with:

CPU: AMD FX-8350 4.0GHz 8-Core Processor ($179.99 @ SuperBiiz)
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler ($30.98 @ OutletPC)
Motherboard: Asus M5A99FX PRO R2.0 ATX AM3+ Motherboard ($119.99 @ Newegg)
Memory: A-Data XPG V1.0 8GB (2 x 4GB) DDR3-1866 Memory ($67.99 @ Newegg)
Storage: Kingston SSDNow V300 Series 120GB 2.5" Solid State Disk ($64.99 @ Micro Center)
Storage: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive ($54.99 @ NCIX US)
Video Card: EVGA GeForce GTX 770 2GB Video Card ($339.99 @ NCIX US)
Case: NZXT H440 (White/Black) ATX Mid Tower Case (Purchased For $0.00)
Power Supply: EVGA SuperNOVA NEX750B BRONZE 750W 80+ Bronze Certified Semi-Modular ATX Power Supply ($69.99 @ Micro Center)
Total: $928.91

I also threw together an Intel system, though admittedly, I'm not all that familiar:

CPU: Intel Core i5-4670K 3.4GHz Quad-Core Processor ($227.99 @ NCIX US)
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler ($30.98 @ OutletPC)
Motherboard: MSI Z87-G45 Gaming ATX LGA1150 Motherboard ($134.99 @ NCIX US)
Memory: A-Data XPG V1.0 8GB (2 x 4GB) DDR3-1600 Memory ($63.99 @ Newegg)
Storage: Kingston SSDNow V300 Series 120GB 2.5" Solid State Disk ($64.99 @ Micro Center)
Storage: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive ($54.99 @ NCIX US)
Video Card: MSI GeForce GTX 770 2GB Video Card ($319.99 @ NCIX US)
Case: NZXT H440 (White/Black) ATX Mid Tower Case (Purchased For $0.00)
Power Supply: Corsair CX 600W 80+ Bronze Certified Semi-Modular ATX Power Supply ($44.99 @ Newegg)
Total: $942.91

Which one would stretch him further for gaming? Or, if there are changes you would recommend to either system, please indulge me.
