The 270x is a great GPU and it will run most games including GTA V on high, however you're going to need to replace that PSU 350W won't be enough for that card, a good 500w should suffice. I however recommend getting a 260x instead and running it in dual graphics mode with your APU, a 260x will be able to run on that 350w PSU and in dual graphics mode with your A10 it'll be able to run most games on high and still come in at $50-60 cheaper than the 270x.

A 260X will not run in dual graphics mode with a 7850K. The R7 250 and 240 are the only ones that will be able to it.

Dont, it runs hot and drivers are bullshit. http://www.amazon.co.uk/MSI-Nvidia-960-Gaming-Graphics/dp/B00SKTY6PS/ref=sr_1_1?s=computers&ie=UTF8&qid=1431285820&sr=1-1&keywords=960the gtx 960 is a better card, runs cooler and has actual driver support.

I would reccomend you a GTX 960,can run GTAV at high detail preset at 50 to 60FPS with no problem.
