In most scenarios, no, I would not use an AMD CPU for a new build.
AMD's APUs are interesting, mostly because Iris Pro is prohibitively expensive for a budget build, and there are certainly some good values in FM2, but the AM3+ platform has very little going for it.
FX CPUs generally have high power consumption and poor performance per watt. This leads them to require higher quality boards with a more robust VRM if one wants to get the most out of them, which in turn leads to platform costs that are no better (and occasionally worse) than Intel's.
There are only a handful of situations where you can build an AM3+ system that has equal or better total performance than an LGA-1155 or LGA-1150 system of the same price.

Even if it has inferior IPC by a bit (due to it being a Pentium) it makes up easily in clockspeed.
A 2.9GHz Ivy Bridge core is quite demonstrably faster than a 3.7GHz Trinity core.
The A8-5500 is still a faster processor, but this is because it has twice as many cores as a G2020 (and a better GPU, as you say), not because the individual cores are faster.

As a games journalist I often suggest configurations for people and at least where I am based ,for sub 800euro systems it is always AMD ,for 1200 and above it is always intel and in-between it is a wash usually.
In the states at least it's still something of a wash when comparing an 8320 setup to the closest gaming-performance-equivalent setup from Intel.
Something like an i5 3350P is only twenty dollars more than an 8320 and can easily be clocked to ~3.7GHz on all four cores with a 60 dollar motherboard, where it will easily match the 8320 in overall gaming performance.
And before someone brings up LGA-1155 being a dead platform, the same statement may well be applicable to AM3+. We do not yet know if Steamroller will make an appearance on it, or what the time frame for this is. In light of this uncertainty, buying for the now, rather than a potential future, is what I would recommend, especially since a usable LGA-1155 board is cheap enough to be disposable.
If you get a board that will let you safely and reliably obtain a significant 24/7 OC on the 8320P, you will close the gap to an unlocked i5.
It's quite possible that NA prices are closer together than in some locations, and that this is skewing the options in some areas.
