So Yuri if I buy the 8320E can I OC it to 4GHZ? and it will be abetter bet than a 8350 running at 4ghz 125W? as the 8320E can do 4GHZ at 95W TDP?
does the stock cooler for the 8320E capable of doing 4GHZ? its the same copper pipe cooler from the 8350?
You'll almost certainly get a 4ghz OC out of any FX chip you buy. An 8320E will likely be able to achieve those clocks while drawing a little less power and producing a bit less heat. Remember though, that overclocked, you're drawing more power and generating more heat than at stock. A 95w CPU is not still 95w when overclocked.
I'm not sure what heatsink it comes with.
I am curious as to why?
seeing that FX 8 core can match an i5 4690K at half the price, in games that are finally taking advantage of 8 cores.
End of the day performance matters and idle the power consumption isn't bad either.
FX-8 is a match for an i5 in some things, and not in others. It's a reasonable gaming CPU though. I'd consider it to be somewhere between an i3 and an i5 (on average) if you overclock, and probably about even in terms of value with an i3 if you plan to leave it stock.
You can expect slightly higher idle power consumption than an equivalent Intel system, but yeah, it's not bad at all. AMD did a fine job getting idle power under control.

That said, if building today and with a very strict budget that doesn't allow for a proper Intel quad, I'd personally still opt for an i3. Mostly this is because there aren't many (any?) decent AM3+ ITX boards, and the extra heat would be a nightmare in a small form factor case.
