Hey, I just picked up an R9 280x. I upgraded from an HD5850, but I'm only seeing a slight increase in performance.
My system:

Intel Core i5 750 (2.67ghz)
16GB DDR3(1600mhz)
VTX R9 280X

Could my CPU be bottlenecking my system? I didn't think the cpu had as big an impact on gaming performance as a powerful GPU, so I thought I would be fine upgrading the GPU.


I tested a few games on ultra settings:
Assassins Creed 4: Black flag - average 20 fps (this seems to be locked at 20, it doesn't waver at all)
Watch dogs: Average 19 fps
Wolfenstein: Average 24 fps
X-Rebirth: Average 16 fps
Shadow Warrior: Average 31 fps
Battlefield 4: Average 55 fps


The good performance in battlefield makes me wonder if my cpu is a bottleneck, or are these other games just not well optimized?


Thanks in advance for any information you can share.

Have you checked you PSU for clean power? It may be under-volting your graphics. Your BF4 frames look about right -- not sure about the others.

What do you mean by clean power? It might be my PSU, I'm using this coolermaster GX 650w, I know it's not really the best. I have a really good Corsair modular psu, but unfortunately it is a bit old and does't have the 4pin pci-e connector.

I know for a fact that battlefield 4 can use more cores than the other games, that is the reason BF4 has good fps, but yes, your cpu is bottlenecking.
I suggest you buy a cpu cooler, something like the cooler master hyper 212 evo and overclock your cpu to around 3.5-4ghz, that would gain you alot of FPS without buying a new cpu!

I think I'll try that, thank you.


[edit] I just did a little overclocking with the stock cooler, just up to 3.1ghz. I'm getting 40-45 fps in watch dogs now. It's running too hot for comfort though, it hits 82oC. I guess a good cooler will solve my problems. :D

If you have reason for concern with your PSU, download and run OCCT.

At the end of a test a window will open with a series of charts depicting voltage delivery for each line in your system. Straight lines are good :D  big drops may reveal *ripple* or volt drops outside of specification for your power supply and/or video card.

With a single rail over 50 amps you should be good for the 280X ... with room for a nice OC for your C2Q.
