Which CPU and GPU would be best for me

I am trying to build a cheap PC mainly to play World Of Tanks and EA racing games like NFS Run and Most Wanted. I was wondering which one of these would be a better build A or B and how can I improve them for minimum cost.

Build  A:
 CPU- Intel Pentium G860
 GPU- Evga GTX 650 1GB
 MOBO- MSI B75MA

 or

 Build B
 CPU- AMD A10 5800
 GPU- Saphire Radeon 6670 (crossfire with A10)
 MOBO-ASROCK FM2A75M

 I kinda want to go with Pentium because I heard there are shutter problems with crossfire with the A10 what do  you think?

 

 

I would spend just a little extra on the cpu and get an i3 3220 the GTX 650 should do you just fine for NFS, but if you can go for the ti edt.

 

Do what you want but you will be happier in the long run with the slightly better cpu and GFX card. Also you will need ram. best to get 8gb.
