amd radeon r9 270x bottleneck?

[speedx]

Hi I wanted to know if my amd radeon r9 270x will be bottlenecked by my amd phenom ii x4 clocked at 3.90 ghz with 8 gb of ddr3 1333. But last of all I wanted to know if a 600 watt psu is causing problems. The reason I ask all of this is because I am getting terrible fps in furmark and in crysis 3.

Thank you in advance

on cpu intensive games like crysis 3 it will slightly, that games is very demanding on the cpu side. on other games that rely on the gpu it won't. on what settings are you playing crysis 3?

what is your psu brand? for a 270x 500 watts is more than enough for it.

 

[speedx]

my psu is a thermaltake 600 watt

I noticed that when I play games that are high intensity the gpu fans slow down and wont speed up

 

[Sig2525]

that is odd anyway fans will only speed up if the temps of the gpu is getting high even if you play gpu intensive games if the temps on your gpu are low the fans will not speed up, your psu is fine looks like it is good quality.

what games are you playing and on what settings? the r9 270x can handle crysis 3 at 1080p ultra but only with fxaa and motion blur off and you will get 30-40 fps average.

i play everything at maximum on 1600 x 900 but I get a framerate of 16 or maybe even 18

why is fxaa so bad for this card? my gtx 650 is smaller older and does better

Not sure about that, but try ticking a few settings down, I know you want the best, or you can lower the resolution to 720 and then you should be able to max things out and play at a higher FPS as Crysis in general is a brutal game for entry level GPU's and older rigs. At your current resolution, ticking the resolution down to 720 won't make much of a difference, only if you really look hard, lol.

I had the option to get a r9 280, should I have gone with that instead

 

[Sig2525]

have you checked? my fps only goes down to the 20s if i set the aa to msaa 8x

you could try to disable aa or just pick fxaa.

i played crysis 3 on 3840x1024 resolution all on ultra and fxaa motion blur off and i get a stable 30 fps.

with your resolution and settings you could atleast get 30-40 fps on max settings with fxaa disabled or just plain fxaa.

 

[speedx]

I disabled all aa and its better but I still have frame drops

what did you upgrade from again? you upgrade your gtx 650 to a r9 270x?..

are you sure to use DDU to completely remove the nvidia drivers then installed the latest amd driver for your card?

 

[speedx]

i upgraded from the gtx 650 to a r9 270x and I uninstalled the old drivers but it seems that my 12 volt rail is dropping to 11.5 when I use the gpu in any way.

But did you do a clean uninstall? Because to me, it's mandatory especially if you are switching makers (Nvidia to AMD in your case). Download Display Driver uninstaller from guru 3D and perform a clean uninstall to get rid of the Nvidia Registry keys and such that are most likely conflicting your your AMD GPU and may be the cause of the odd power usage.

If possible, try another PSU and see if you have the same issues after doing a clean uninstall and then installing the latest drivers for your AMD GPU.

+1 for this the DDU is the one of the best gpu driver uninstaller out there.

 

[speedx]

I will try duu but you are sure it is supposed to do more than it is doing correct?

 

[speedx]

Well DUU worked because I am getting 30 to 40 fps on furmark with all filtering on high and crisis works an maximum with all filtering on max as well!

Thank you to all the people who helped

Glad to hear that, Happy gaming!
