Help me decide on a new PC!

[Soft Shock]

These are parts I chose from PC Part Picker and are ready to buy:
Intel Core i5-3470 3.2GHz Quad-Core Processor
Asus P8Z77-V LK ATX LGA1155 Motherboard
G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1866 Memory
Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive
EVGA GeForce GTX 780 3GB Superclocked ACX Video Card
Fractal Design Define R4 ATX Mid Tower Case
SeaSonic G 550W 80+ Gold Certified Semi-Modular ATX Power Supply
Windows 8.1

This is a PC from ibuypower.com:
Intel® Core™ i5-4460 Processor (4x 3.20GHz/6MB L3 Cache)
16 GB [8 GB x2] DDR3-1866 Memory Module - ADATA XPG V2
NVIDIA GeForce GTX 780 - 3GB - EVGA Superclocked
Gigabyte GA-Z97-D3H -- 1x PCIe 3.0 x16, 4x USB 3.0, 6x SATA-III 6Gb/s
850 Watt - Corsair RM850 - 80 PLUS Gold, Full Modular
256GB ADATA SP610 SSD + 2TB 7200RPM HARD DRIVE
Raidmax Cobra Gaming Case - Blue
Windows 8.1


I'd have to build the PC Part Picker Build myself. But ibuypower builds the computer.
From PC part picker the total would be $1,723.62. ibuypower would be $2,173 (I chose expensive shipping and handling) So should I build my PC or should I buy it from ibuypower?
Are the parts I picked good enough from PC Part Picker? And will these two builds play games on ultra graphics?

Find a i5 3570k and add a SSD then the first build list will be similar to the ibuypower one. You could also get an i5 4690k and a Z97 motherboard which allows upgrading to Broadwell cpu in the future if necessary.
If overclocking the cpu, add an aftermarket cpu cooler.
Building it yourself is always cheaper, however, if you don't have the time then getting the ibuypower is probably the best option then.
Both will play ultra settings at 1080p

Thanks for the fast reply, I'm going to look into that CPU and SSD for the PC Part Picker Build, it seems like I would be fun to build a PC instead.
