Upgrade \ prepare parts recommendations

Because my mother board /CPU Brock and I neaded an upgrade for gaming and video editing for a 300 to 450 dollar budget point I turned to this form

Working parts

600 watt corsair power supply

Atx corsair case

8 gig 1600 ddr3 ram

2 terabite drive 

Amd 7950 ( I can sell this GPU if I upgrade it)

Non working parts ( not sure wich one broke)

A10-7850

Asus fm2+-pro

What country will you buy your parts in and what currency?

here is an fx 6300 CPU on an Asus m5a97 mobo & CM212 evo  cooler and an R9 280 GPU $426 USD

I'm in the USA and I use dollars and isn't a 7950 equal to the r9 280 ? 

 

But thank you for your suggestion

Aside from different clock speeds, yes.
