1. Effectively, there will not be a bottle-neck if each component is capable of relaying data at precisely (or approximately, for argument's sake) the same rate every other component is able to process it at, but a balanced system as such isn't likely to exist, simply because different software are optimized to take more or less advantage of different components. You can identify these optimization differences between games, but to be clear, for instance, if you're editing video, the CPU plays a more relevant role than the GPU; the opposite is true for gaming at high resolutions (1080p and above), where a more powerful GPU affects the image quality and frames-per-second, for instance, more than a CPU does.
2. V-sync helps with a bottleneck because it limits the amount of frames-per-second displayed (dependent on the refresh rate of the monitor, as you correctly point out), which in turn relieves the gas throttle on the GPU and allows it to work at a lower .
Consider now a monitor with a refresh rate at 60 Hz and a CPU that doesn't limit the GPU: the former has a comfortable data-processing clearance over the latter, simply put. Without v-sync on, the GPU will limit the system and the amount of FPS displayed are on average 76, to exemplify. V-sync is turned on and now, the amount of frames being requested rolls down to 60. At this point, the GPU still has an average clearance of 16 frames-per-second, which means it no longer is a limiting factor where maximum FPS are concerned. In short, v-sync gets to be the bottle-neck, relaying the GPU.
Note: This doesn't have much of an impact, if any, on minimum FPS, which will be similar to v-sync-disabled values. The average will therefore be lower (with v-sync on), given that maximum FPS are limited, but as stated above, the limitation is the feature, not the GPU, which is why the bottle-neck is alleviated.
3. At this point I reckon I've elaborated sufficiently for you to solve your proposed problem above, but given that you'll be the judge of that, I'll add that as a rule, you address the bottle-neck by ameliorating (over-clock'ing) or upgrading the least powerful component, which in your particular case would be the CPU. Per my analogy, if you were to replace the HD 5770 with a less powerful GPU, then whatever limitations the CPU was causing, would still persist. If any, you would be forced to lower the visual settings and the GPU would then become the limitation; otherwise, no difference whatsoever.

Hello friends, been quite a while; I have been studying for my CompTIA A+ certification, so I havent had much time to post. Thank you for your patience.
1. Okay thank you, I believe I understand this clearly now; so, for the most part a bottle-neck will always exist due to different hardware specifications and also due to the way that software sporadically accesses random components at different data rates?
Also, you are stating there are ways to make the bottle-neck not as noticeable such as below (vsync), am I correct?
2. So, in short: It allows for more processing room (GPU), which alleviates bottle-neck issues because it doesn't have a hardware limitation (instead room to breathe) and in turn makes data transfer more synchronous; am I correct?
3. I believe I am starting to understand this more clearly, I was under the impression recently that a bottle-neck just meant that I didn't meet the maximum system requirements for certain components; so I thought that was why I needed to upgrade my CPU (possible limiting factor), but it seems there is more to this: always a bottle-neck, software is generally a cause along with hardware sending different data speeds. This is all a bit confusing, but I think I finally understand.
Ah, another note: Due to an error that occurred after an install, I decided to reboot my PC; as we both suspected CCC was able to become fully active again, I will note however: (capitalized for all having similar issues) I DID NOT INSTALL ANY OTHER DRIVERS AFTER THE FORMAT AND RE-INSTALLATION PROCESS, I ALMOST INSTANTLY INSTALLED THE CATALYST CONTROL CENTER FOR MY GPU AND NOW EVERY OPTION IS AVAILABLE.
Thank you for your time friends and heres to hoping for the best; tax time is around the corner and there is still a few of my CPUs available on the market. I must say the CPU seems quite amazing with the L3 cache that I have just recently learned about; I am very excited about this upgrade.
Until next time friends.
