Is This A Good Build????

Hey this is my first time building my own computer and I was wondering if people more experienced than me thought this was a good build.
I will be using this computer for medium amounts of gaming, programming, and surfing the web. I would also love it if you could give me feedback and tell me if there was anything else i needed. (soundcard e.t.c.)

CASE:
COOLER MASTER HAF 912

PSU: COOLER MASTER Silent Pro Gold Series RS800-80GAD3-US 800W ATX

HDD: Hitachi GST Deskstar 7K1000.C 0F10383 1TB 7200 RPM

MOBO: ASRock Z77 Extreme4 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

GPU: GIGABYTE GV-R787OC-2GD Radeon HD 7870 GHz Edition 2GB 256-bit GDDR5 PCI Express 3.0

CPU: Intel Core i5-2400 Sandy Bridge 3.1GHz (3.4GHz Turbo Boost) LGA 1155 95W Quad-Core

RAM: G.SKILL Ripjaws Series 12GB (3 x 4GB) 240-Pin DDR3

Disc Reader: ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner

All forms of help are appreaciated

P.S. I have already chosen my mouse, keyboard speakers and monitor.
P.S.S. If you have seen this tread before it was because I accidentally inserted it into the wrong category.

Could you also check for compatibility between the parts of the computer. I have tried to do this but I am not experienced and may have missed some key points in the build.

Such a noob
