Hello,
The A88X-G45 is a good quality motherboard, just bear in mind that the APU needs a very fast memory for fully utilize the built-in graphics (the faster the better, 2133 or 2400MHz; also, the lower the latency the better). You can expect acceptable gaming performance in FHD (1920x1080), between 20 and 50 FPS, with low-medium details. Also, remember to go for a good aftermarket cooler.
However, if you are not an avid gamer and you don't want to overclock, I would go with this (the A10-7850K is overpriced for what it has to offer):

It will be faster than the A10-7850K in any usage scenario except games, and when you will have the budget you can add any graphics card (260x or 750Ti, for example) for much better graphics performance. Also, you can use lower clocked memory (1600MHz is the sweet spot) which is cheaper, and the stock cooler is all it needs.
