so the bottleneck website will give an idea if the 5 years gpu is compatible with my current rig
Some times people build PCs that are not balanced due to lack of knowledge, budget or user needs. like i3 with GTX 1080 or i7 with GTX 1060. A bottleneck happens when one component is much slower/faster compared to other parts. This site can help achieve a balanced build when upgrading.
Or you could ask here for recommendations 5 years later or whenever you wanna upgrade.
-------------------------------------
If you wanna OC your GPU now or have a reference guide, here:
0. Install MSI Afterburner.
0. Download and run UNIGINE Valley on Ultra.
1. Max your power limit. (500W+ PSU recommended)
2. Increase your core clock 50+ at a time while looking at UNIGINE benchmark till artifacts (weird lines and colors) appear or your driver crashes. Then fine tune it compared to your previous clock.
Example Core clock: +50 > ... > +150 > artifact > ... > +120 (Keep it 25 or more below max)
3. Do the same for Memory. (50 or more below max)
4. Save your profile.
5. Don't check apply overclocking at startup. You can check it after few days.
Keep all your temps
below 80c/176F, if you go over it or stay near it., consider installing fans and cleaning case.
Overclocking is safe as long as you keep it cool and don't push it too much. That's why we determine the max OC first, then we lower it to so chip doesn't work too hard.
