Choice of Motherboard is really bad. Extreme 4 is known to have certain issues with the VRM design. Assuming you already have 10K for GPU, 14K for CPU and 10K for Motherboard, here is my suggestion:-
FX-8350 @ 11.5K
MSI 990FXXA-GD65 @ 9.2K
Sapphire HD 7870 2GB GDDR5 @ 16.5K
Total: 37.2K
If you are asking for a gaming setup then this one is far better than the one you have decided. Getting a lower-middle end GPU along with a costly Processor does not serve the purpose of a gaming PC, you need proper balance between them. FX-8350+ HD 7870 combination will perform far better than the i5 3570K + GTX 650 Ti combination in gaming.
