Hey guys,

I've been talking with a friend about PC gaming. He is interested in the world of high-end PC gaming, however he already has an average PC with an A8 APU. (specs here http://)

So we talked about the possiblity of upgrading his current machines GPU, but as you can see it only has a 300W PSU. I am more of a build from scratch guy so when we get into pre made machines my knowledge begins to waver. So my question is, would it be possible to upgrade his PSU as well as his GPU?

You should be able to use any ATX form factor PSU in that case.

Definitely. That computer uses a normal ATX sized PSU, and a full PCIe 2.0 x16 lane. That will be able to support and fully power any single GPU card on the market right now just fine. a good 550w PSU and a 760 would get him into High/Ultra for around $300 or so.

Thank you so much! But would something as powerful as a 760 cause a CPU bottleneck?

In games like BF4 you would see FPS drops in multiplayer action, but for most GPU-bound games, there won't be too much of a slow down. Either way, though, you'd get better performance than buying a slower one! lol Most games are much more reliant upon the GPU, so the older CPU wouldn't be too much of a bog.

Would it make more sense though to get a 750 Ti or a 660?

To be more balanced, yes, but you will get markedly better performance with the 760. Plus, with the 760, if he does upgrade in the future, a 760 would last much longer.

Ah okay cool. So I think something like this (http://) would be a good upgrade.

Yeah that would be perfect :)  That PSU has enough power to run anything you throw at it if you keep to a single graphics card :)
