You could save some money by not buying a monitor and just using your TV, the extra money could go towards future upgrades.
I would go with the AMD build, seen as the 6300 keeps up pretty well with the i5, yes it's abit behind, but in game, you're not going to notice that difference, And taking into account you plan to overclock, AMD seems like an even better choice seen as an OC'd 6300 is on par with the i5.
if you gonne use only one video card for now and in the future i preffere to chance youre motherboard and cpu, cause then you dont need the 990 fx chipset.
a 970 chipset is about 60/70 dollars cheaper ( Asus m5a97 evo r2.0) and its enough for ya needs. the money you saving for that you can buy a better cpu an Fx8320 of 8350 :)
