Hey ! I've been looking for new GPU. I play WoW and CSGO as my main games and i came across HD 7850. Would it be good idea to buy that ? or should i go for R9 270 ? I got A10-6800K CPU and Super Flower 450w, Golden Green HX, 80Plus Gold PSU.

You got an excellent PSU in terms of quality, tier 2 class A according to this list:

7850 uses slightly more than 110W, and your full build cannot even reach 300W, let alone 500 which is a "requirement" for this card.

Also, 7850 needs 21A on +12V rail, your PSU provides 37A.

It is safe to go with 7850 with your current PSU. You can even use R9 270X no problem with your current setup, as long as you don't go crazy on overclocking.
