He's a fanboy. It oozes even from your forum post. You should always go with what you can afford, and as long as you game on a monitor that's big enough to make the video card do its work, there's nothing wrong with the Phenom II, especially the 970. I'm all for the i5 and i7 these days, but I also own several Phenom II's and they're fine chips.
I don't see anything with your build other than the PSU. I used to swear by PCP&C power supplies like other folks did, then OCZ bought the brand and now they really suck (i've had two go south on me, when they never used to) so I buy Corsair units now, both at home and at work.
You are of course free to go with who you like, but I take power very seriously.
