Building my first gaming computer?

My budget is $500 so this is what I have picked out so far. Please let me know if I should get something else (within the same price range). I hope to get at least 120 FPS while playing minecraft.
Heres the specs:

CPU: AMD Athlon X4 750K 3.4GHz Quad-Core Processor ($79.98 @ OutletPC)
Motherboard: Asus F2A85-M PRO Micro ATX FM2 Motherboard ($74.99 @ Newegg)
Memory: Kingston 8GB (1 x 8GB) DDR3-1600 Memory ($63.99 @ Best Buy)
Storage: Western Digital RE3 1TB 3.5" 7200RPM Internal Hard Drive ($52.26 @ Amazon)
Video Card: MSI GeForce GTX 750 Ti 2GB Video Card ($164.99 @ Amazon)
Case: Logisys CS368BB ATX Mid Tower Case w/480W Power Supply ($33.99 @ Amazon)
Total: $470.20

It seems a very decent configuration for mainstream gaming all components are chosen wisely but as you have a very strict budget there are very little head room for upgrade (specially cpu is little bit under powered). This game will run smoothly in this setup but regarding 120 fps I don't know that. I would suggest why don't you have a look at the apus from amd. Choose a good a10 apu and combine it with a compatible Radeon gpu and run it in hybrid crossfire. In same price you can get a better performing gaming pc. Have a look at the prices,

the link above is a review look at the last review. The granddaughter plays minecraft. The APU I listed is a newer better version.

As for a motherboard go with this one.

76.99 and it has a rebate which makes it 61.99
You won't need a videocard with this setup so spend the extra money on more memory.
everything else is good. Your memory is compatible with the motherboard i selected.
