Except a 4790K @ stock would blow this away with a fraction of the power used:

and you won't need to worry about melting VRMs on cheapo AM3+ boards.
Saving money with FX is a myth. You may as well get a locked i5/i7 with an H97 board that will cost more but give you a way newer platform and cooler/quieter chip to boot. If AMD carries on with this rubbish their FX CPU division will cease to exist and will revolve entirely around APUs.
Current popular opinion is that the FX line and desktop CPU's in general have in fact ceased to exist. What are these things, three years old now?
The price tags don't look like a myth to me though still.
I looked really hard at that $300+ i7 before I bought my 8350 (for $180 at the time and then bought a 9590 for $230ish later, because fun). I looked at the performance I had from my 955BE that I'd had for years, I looked at the performance I'd had from a 1090T for a few months. I looked at the benchmarks that showed i5's and i7's seemingly so much faster than the FX. I looked at them compared to the 1090T I had at the time. I decided something didn't make since because that 1090T honestly was plenty fast with few exceptions. So I looked harder at the benchmarks. After some pondering, I decided to save a hundred bucks and bought the 8350, and it performed admirably. As does the 9590. I've no doubt the Intel stuff benches better, but it is my personal and experienced opinion that benchmarks the way they are related online do not reflect adequately a true user experience. I spend 18 hours a day in front of this screen for work and pleasure, if it was in any way slow or annoying, I'd replace it in a heartbeat. I haven't yet. And despite buying one of if not the most power hungry and hot running CPU's in existence, I can't tell it. My GPU's dwarf the heat production and power usage of the 9590, which is at nearly idle most of the time anyway. My utility bill is the same as it was last year (i checked). My case is still 30C this time of year, socket is 33C, might see mid 50's gaming. Yawn. The power/heat bit is overblown to me. To each their own though.
One myth is, that a cheap FX does not offer a perfectly adequate user experience, gaming or otherwise, in/to the vast majority of situations/users, despite it's sometimes low benchmark scores. What you read on a forum or review site does not always translate into real life.

This fellow has done some interesting work here, mostly demonstrating that a budget CPU with a better GPU is preferable to an expensive CPU and cheaper GPU, but overall it does a good job dispelling the FX isn't good for gaming bit, which is also a myth.
There are a few games that can't adequately use an FX, but personally after seeing how Crysis 3 and BF4 and anything else I've found to try runs on my system, I'm not willing to accept excuses for shoddy software anymore.
As far as I can tell you should buy Intel if you can afford it and/or if image and benches matter to you, or more importantly if you actually can use the speed increase they offer. And it's ok if image and benches do matter to you, lots of folks are that way. If you're a cheap SOB tinker like myself and are concerned with how things actually perform and get a kick out of eccentric non-mainstream machines and making them work better than everyone else, the FX will likely have something to offer you. It's a shame we're all going to find ourselves at the mercy of Intel in the coming years for desktop CPU's unless something drastic happens. Luckily performance has been increasing so slowly I don't see the legacy FX line ceasing to be relevant for a long while.
Oh, and I have an i7 laptop which is very nice also, so I'm not especially biased.
