New PC...

Well I made a new PC:

CPU: Intel Core i7 4770 (3,4GHz, Sockel LGA1150, 8MB Cache) boxed
GPU: Zotac NVIDIA GeForce GTX 770 (PCI, 4GB GDDR5, DVI)
Mainbord: MSI 7821-001R Z87-G45 Gaming Intel Z87 Mainboard Sockel LGA 1150 (4x DDR3, Intel HD Graphics, 3x PCI-e, 6x SATA, ATX)
Power Supply: be quiet! BQT E9 Straight Power (700 Watt)
RAM: Corsair Vengeance 16GB (2x8GB) DDR3 1600 MHz (PC3 12800)
HDD: Seagate Barracuda ST2000DM001 2TB (8,9 cm (3,5"), 7200rpm, 64MB Cache, SATA III)
SSD: Samsung MZ-7TE120BW Serie 840 EVO Basic SSD(6,4 cm (2,5") (120GB, 256MB Cache, SATA III,)
DVD Drive: LG GH24NSB0 DVD 24x
Case: Thermaltake VO700A1W3N Versa G2 Midi-Tower (ATX, 3x 5,25 , 5x 3,5 , USB 3.0)
Monitor: Asus VS248H 61cm (24 Zoll) LED Monitor (VGA, DVI-D, HDMI, 2ms)
Keyboard: SteelSeries 6Gv2

The GPU isn't good enough for the CPU right?
Anything else I should improve?
Did I forget anything? (I know that there is no mouse...)
This is just something I made quickly.... Please leave some suggestions here...
If you think this is completely crap you can give me another build for under 1500€
