You didn't state whether or not you need an OS so one is included, and if you don't need the HD space don't get the HDD. Pretty much bounce around the SSD/HDD/OS to fit what you need/want, as long as you subtract one of them you will easily fall within budget. though the SSD will make the system feel significantly faster, especially with what your planning to do.
That is an AMD APU. I went with the AMD APU due it having a better GPU than intels offerings and find that you are typically more GPU restricted more than anything in my personal experience when dealing with integrated GPU's than the CPU.
And for the price there are better things than the G850.
