GPU upgrade gone wrong! HELP!

I've got a very strange problem due to a video card upgrade.

I upgraded from a nvidia 460gtx to a amd r9 270oc and my computer is acting like it has had a stroke! Extremely slow performance in desktop and web browsing. Strange stuttering effect that happens consistently, renders bf4 unplayable and is even noticeable in Hearthstone! It's hard to explain but take my word for it, it's like my all around computer performance has be cut down to about 33% in all aspects. A thing to note is that in bf4, what i've been using to trouble shoot, if I change the settings from low to ultra no real difference occurs. The stuttering effect remains apparent.

Steps I have taken:

Used Display Driver Uninstaller (DDU) before any drivers were tried
Newest version of drivers
Beta drivers
Legacy Version of drivers
Disabled onboard Video
Used multiple OC tools to boost voltage to card
Put old card back in (works fine)

I feel like I have tried more things, but can't recall at the moment. I have searched so many posts online I'm not sure there is anything left.

My computer:

i5 4670k
8gbram
windows 8.1 (updated)
gigabyte r9 270oc 2gb
725watt psu
gigabyte z87x-d3h MOBO

Like I said, i upgraded from a 460gtx to the r9 270 and it's like my computer has gone back to the 90's. Very, very shitty performance.

Details of behavior:

It is a stuttering effect where in games it moves smooth, chokes up (strokes out), then repeat at very quick intervals of about 0.5-1 second. The computer struggles to load maps and web data. The way the computer is behaving I feel like it is a cpu problem but everything checks out so far.

If you have any ideas please let me know! This has become a personal battle for me now and I refuse to lose!

Thanks for your help toms guys, you have bailed me out in the past please do it again! I am desperate for a solution.

Cheers.

Monitor your GPU clocks while gaming,are they consistently as high as they should be?

Check your CPU temps out.
725w PSU sounds a bit fishy. What brand is it?

Okay here is something odd. Overnight my intel hd grafix re-enabled itself. I didn't do it. It is showing up in afterburner and is being used! Is there a fool prrof way to disable it permanently? (i've only ever used device manager)

my r9 270 does stay at the correct clock speed while gaming.

Thanks for the insight and concern.

It is a coolermaster 725w EX2 psu.
Afterburner says that my cpu temps are 100degrees while gaming and only dropped down to 90 consistantly while in idle. Its even for all 4 cores.

Seems strange. Thanks for you help.

That is your problem! Thermal throttling.

Looks like maybe you knocked your CPU heatsink when you were changing GPUs?

The PSU isn't a high quality unit either

What I would do is take off the the CPU heatsink fan, clean off the thermal paste from the CPU
and heatsink and then reattach it. Make sure it sits tight on the CPU and the fan wire is connected

Okay so I pulled it out and re installed before i saw about cleaning the thermal paste off. That solved everything! Game loads what seems to be instantly now and runs flawlessly, ULTRA!! As a note the cpu temps went down to about 30 degrees idle to 50 when loaded. Is thermal paste removal necessary? Should i re-apply new paste?

Crap yes I meant remove and then reapply sorry.

But your temps are acceptable now so you could leave it as is.

Ill keep an eye on things but will get new paste once im nearby my local shop. Thanks for all your help man! I feel like a knob for not noticing that and struggling for 3 days trying to figure it out. Lessons learned the hard way are good lessons indeed. Thanks again for your assistance and timely replies.
