[Kyleezzy]

Questions

1. Which is better

2. Which gpu will work with the apu to do dual graphics

3. If single gpu is better which gpu will it be (budget wise and will be able to run Overwatch)

Specs: A68 hm grenade motherboard, 8 GB ram, A8 7670k CPU

Single best GPU all teh way.
According to your budget, get the RX 470 for ~150 at teh and of teh month or teh RX 480 for 200.

1. Single GPU is better than dual graphics if the GPU is good enough.

2. Dual graphics on an APU is limited to the power of an R7 250.

3. To answer this one, we need to know what model and power PSU you have to make sure it can power the best GPU.

You can see here : http://www.anandtech.com/show/9320/intel-broadwell-review-i7-5775c-i5-5675c/8?_ga=1.240284807.589369490.1464733707 that your CPU limits even an old GTX 770 or a R9 285. Other benchmarks with slightly different CPUs suggest that a modern GTX 960 will be limited too. You have a fairly weak CPU and modern games are getting more demanding.

Once we know about your CPU, we can make better recommendations. The GPUs suggested above might not run on your PSU.
