Intel i5+amd r9 270+ MSI ms7826 vs Intel i5+Nvidia gtx650 + MSI ms-7826 for games

Hello, I am upgrading my son's HP Envy 700-074 which comes with an integrated HD 4600. I Bought a used R9 270 and there just doesn't seem to be a boost in performance, although the spcs of the latter demolish that of the former.

Is there some issue with AMD gpus working with Intel CPUs? Should I buy a Nvidia 650 Ti to replace the r9 270? I've been researching for months, and no one site will give a definitive answer
thank you

The 270 is WAY WAY better than the 650ti. No there is no issue with AMD GPUs and intel CPUs at all. No issue at all.

Do you have the monitor connected to the GPU, not motherboard?

Is the GPU getting power from the PSU via the 6-pin connector?

There are no issues with AMD GPU's and Intel CPU's, if there were AMD would not be in business by now.

I assume You have installed the latest AMD drivers for the 270? Nvidia 650ti is less powerful than a 270 so that
would not be a good idea. Make sure You have turned off (if possible) the onboard video in the bios, and obviously
plug the monitor into the new cards video port (Sorry but I have seen people make this mistake)
Another problem could be that you need to remove any and all traces of the old video cards drivers, You can get a
free driver cleaner program from Guru3d. After running install the new AMD drivers.
Install latest Directx as well as Directx9 for titles like COD that still use it.

GPU is plugged into PSU
monitor is plugged into GPU
I just ran Windows update, 42 critical updates, 5 extraneous, then downloaded the nov 2014 driver, already has the latest Direct x and Open Gl, (12, requires 11)
Installed latest AMD catalyst control.

Seems faster, I don't know what games he is playing, he is out of town for weekend. I think that got it.

machine was flickering and green screening, then locking up with the original install on the r9 270.

We will see
