I wouldn't say it would bottleneck you. It's not the fastest proc but it's certainly not that bad.

You should be able to house most of the FX series of processors if you wanted an upgrade but I would first upgrade your noname PSU.

The CPU isnt good in that there are much better options at its pricepoint, but it wont perform that badly.

While Devil May Cry isnt the most graphically or CPU intensive game, if your getting 60FPS that's great. That the max FPS you can have while Vsync is enabled (keep it on unless you have a 120hz monitor).

If the machine is performing adequately in what you want, there is no need to upgrade or change anything.
EDIT: Except maybe the PSU. That should be changed to something more reliable.

I agree with Manofchalk. If the PC does everything you want then there is no need to upgrade. Don't upgrade based on what your mate uses his PC for.

Maybe a PSU change isnt needed then. While Coolermaster isnt the greatest name in PSU units, they at least have a reputation as a budget brand rather than a horrible one.

A Coolermaster PSU shouldn't blow up at least. It will also handle a cpu upgrade if you do decide to get one

Bottlenecking is when the GPU usage isn't reaching high percentage and you suffer low framerates.

For example is you were getting 20 fps but your GPU usage was only at 40%

CM PSUs are near-junk, especially at the low end. Don't count on it for more than 430W; monitor the temperature of the air coming out of it during a long gaming session. It may also be missing claimed protection circuits (some of their low-end are). Short answer, I'd suggest replacing it with a quality unit. Five hundred watts is enough, but choose a quality brand like Seasonic, XFX, Antec, FSP, or Enermax/LEPA.
While I wouldn't buy a FX-4100 myself, if your games are running to your satisfaction, then I'd leave it alone.

il change my psu then,what about this processor should i replace it with i5 3rd gen? store keeper compromised me with all those specs like 3.6 ghz speed and 4 cores and 12mb cache ...but got to know later that this actually is merely dual core with 2 sub cores and also that amd scAle of calculating the speed/frequency is a way smaller when compared with intel. !!

64.7 FPS uniengine heaven 1920, 4xMSAA, 4xAF with the X3-455 in the below rig; A 4100 definitely won't bottleneck a 7850 :) 

enjoy!
