Here's the deal I don't own a FX 6350 but if it's average FPS is not 60 with a top of the line graphics card than I think of that as bottlenecking. Everyone's monitor should be be at least 60hz so 60FPS will be a postive. Even worse the AMD CPUs tend to have a lower minimum FPS which is one reason why the avg FPS would be lower than an Intel. If you want the smoothest FPS Intel is still the winner. It's those drops from 50-60FPS to 30 or maybe 29FPS that makes me irratated (that an stuttering). The thing is a person does not need to be a competetive gamer to play at 60FPS+. I don't want 144FPS I just wan't as close to 60FPS like monitor or 75FPS if I select a higher refresh rate. From personal experience 30FPS vs 60FPS is pretty big so that's why I gave my opnion (and numbers from other sources.)
OK but my point is what makes you believe that an FX6350 is incapable of maintaining 60fps with a high end graphics card?
I agree that 60fps should be the target to aim for and frame rates of 30-40fps is only really acceptable for casual non action games. Also big fps drops are a no-no. However, gaming on the whole is not hugely CPU intensive (there are exceptions to this of course). I have yet to see significant evidence of this fabled bottlenecking on any modern hardware unless we are talking seriously high end... as I mentioned before. I think we are still stuck in the dual core core2duo and Athlon days sometimes. Yes these CPU's will effect your performance but since we have started playing with 3.0ghz + performance and 4 cores (or even hyperthreading with i3) for most people they will not experience CPU bottlenecking @ 60fps. You are more likely to be bottlenecked by running say an FX6350 on some totally pants 760g chipset (why do they still sell this tat?) and your VRM's are overheating and literally throttling your performance. Most AMD motherboards struggle to handle the power draw of the FX chips. This is again why I think the 95w TDP FX6300 is the sweet spot for 60fps 1080p gaming.
I can also say this because I have an i7-2600 @ 4.2ghz and my girlfriends FX6300 @ 4.0ghz right next to mine performs almost exactly the same (we have matching monitors).
Am I trying to argue that bottlenecking doesn't exist period or that AMD's perform the same as Intel. No I am not, but in response to the OP and his question about a CPU change I am saying that there is a reason why the FX6300 always is on the best CPU's for your money thread right here on Tom's and it isn't because it can't handle 1080p gaming.
