intel+AMD or AMD+AMD? light casual Steam gaming build thoughts

[giantbucket]

i already have an intel+nvidia machine that's my office/games machine, but it's at the office. i'm thinking of doing another for home, but for variety i'd like to use an AMD graphics card.

given that i'm a light/casual gamer, i'm going to keep it to low/mid-range parts. all games are Steam, played at 1080p (TV), and i don't need all settings on ultramaxinsanetruelife3dyoucansmellit.

intel = i3-4360 maybe? or even G3258 and OC it? (for info, office/game machine is i3-4130 + GTX760)
AMD = A8-7600 maybe? FX-6300?

which is a better / more interesting platform? i'd buy and keep the CPU, no upgrades after N months. no idea which specific GPU i'd pair it with, but no wilder than r9 280x based on prices (the $180 Canadian to $250 Canadian price range)

Ironically all AMD builds are known to suffer issues and perform worse than Intel and AMD builds - even with completely performance matched CPUS. Go with Intel, and whichever graphics you choose. You'll get far better performance.

I recommend Intel cpus at every price range and AMD gpus under $300

will the G3258 (with or without OCing) be able to play Steam games? i've read that the lack of 4 cores or hyperthreading prevents some games from even working in the first place. is that only for standalone stuff, or Steam-based stuff as well?
