AMD chips are just lower performing, less expensive chips. an Fx 6300 is a great budget processor. Intel's best budget offering is the G3258, which is a 2 core processor.
There isn't really an AMD competition after that. The 8320 processor is basically the same as the Fx 6300 with 2 more cores, which isn't any more helpful for gaming, so thats where the I5 is going to come in, as the higher performing chip.
Don't be fooled by fan boys, while the intel processor is definitely better, its not worth the money if you don't already have a really great Graphics Processor/Video card, as that is the most important for gaming.
Also, for the last item you have, what is a stabilizer?
