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.

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.
