No they don't. I love Intel, but saying AMD sucks is the mark of a fanboy. Their APU's are good, and their Phenoms are good, cheap quad-cores for those on a budget.
Saying AMD sucks for gaming without providing backup when challenged is the mark of a fanboy.
In the comparison of sub-$200 CPUs from a gaming perspective
, Intel's offerings blow those of AMD out of the water:
To quote that article, since many people tend to be too lazy to click through:
With the sub-$100 Pentiums performing so well, Intel's $125 Core i3-2100 easily beats more expensive Phenom II and FX models. And the $190 Core i5-2400 dominates the sub-$200 landscape without challenge, really. As such, we're almost-shockingly left without an AMD CPU to recommend at any price point.
While it’s true that AMD’s multiplier-unlocked models appeal to tweak-happy power users, the company's overclocked game performance manages to either hang close to or fall just behind Intel's stock Core i3-2100. Pumping up voltage, multipliers, and, consequently, power usage seems like a futile exercise just to keep pace with an efficient $125 budget-oriented chip running at its default settings.
I try to not be a fanboy, but Intel does make it difficult...
EDIT: more reading if you are so inclined, as far as BF3 performance goes:
In a nutshell, single-player is almost entirely GPU-limited. Multiplayer, as you get on to 32- or 64-player servers, tends to shift towards CPU-limited. Thus I strongly recommend aqualipt's build, if you can shell out the extra $33
