I agree with tiny; if you're buying a graphics card don't go APU. Also, can you get the phenom II, or athlon II x4 chips near you? A phenom II might leave you with enough for the 7850, and you can upgrade to piledriver/steamroller whenever, as the newer chips will be compatible with your motherboard.
After reading a few reviews I also agree with tiny; Closest I can get is Athlon II x3 3.2ghz. Phenom or an athlon x4 isn't.
@tiny, indeed I will get an i3. most of the answers here prefers and i3. If I'll push a 7850, I'd probably have to wait a month for it.
quick question regarding the RAM PSU and Motherboard.
Gigabyte B75M D3V/Asrock B75M DGS for motherboard?
is the G.skill ram good as a brand?
is the PSU at 450w enough to run this build?
