Opinions on my gaming machine

So hey guys I built a gaming machine with money i had saving and this is what I made. Is this good or did I do something wrong.

Is this a good gaming machine I built:

CPU/APU: AMD A8 5600k 3.9 Ghz Quad Core

Motherboard: Asrock FM2A75 Pro4-m

PSU: Chieftec GPS 700A8 ( bought this on sale)

RAM: Corsair Vengeance 4Gb 1600Mhz(gonna put 8Gb in a month or so)

HDD: Seagate Barracuda 1Tb, didn't buy an ssd they are too expensive in my country

GPU: Sapphire HD 7770 Vapor x 1Gb( also going to by one more or maybe 7850 to put in crossfire)

wait, I don't think the a8 can hybrid crossfire with a 7 series card...correct me if I'm wrong.

Also, the new Richland APU's will be releasing in march 19, if you wanna sit tight for a bit, not sure about the costs..but maybe the current ones will go down a bit possibly.

Correct,the A8 can only crossfire with the 6670 (the highest).

I wasn't looking to crossfire the apu with the card. The motherboard itself has two pcie ports for two gpu's. And I was thinking of buying another card in may or june. Maybe 7870 or 7850.I could sell my 7770 now and buy it already but i want to see how it performs in crossfirex

Just checked in the manual. It can hybrid crossfire with any card but its reccomended to crossfire with 6670 for optimal performance
