Good gaming PC for 800-900 euros?

[stefan37]

Hello I'm a noob with this and this will be my first time building a gaming PC on my own. I'm from Serbia and I'm gonna buy it in september.
Specs:
CPU: Intel i7 2600k - 254 euros
Mobo: Asus P8Z77 - V Deluxe - 199 eur
RAM: MUSHKIN
8GB (2x4GB) 2000MHz DDR3 Blackline 996990 - 56 eur
GPU: SAPPHIRE
Radeon HD 7850 2GB GDDR5 OC - 221 eur
HDD: WESTERN DIGITAL
Caviar Green 1TB 32MB SATA300 WD10EADS 88 eur
PSU: I don't know which one would be the best...

Please tell me if this is good and what PSU and cooling should I use?

i5 3570k - better bang for your buck. don't need i7 for gaming
Gigabyte z77x-ud3h or Asrock z77 extreme 4 - Cheaper MoBo alternatives with good features
Mushkin Enhanced Blacklyne Frostbyte 1600 Cl9 1.5V (2 x 4 Gb) - Performance gained with faster RAM is minimal
Mushkin Chronos SSD 60 Gb - Use this as a boot drive and your HDD as storage
CM Hyper 212 EVO - CPU cooling fan

500 - 550W should be enough unless you plan on xFire or SLI in the future. Just make sure you buy a PSU from a reputable brand and reliable model. I really like the XFX Core Edition 550W.
