Is there a way to analyze and find the bottle neck in the system? I guess most will say is the RAM but i'm using it mostly for web development, and none of the software is too heavy
Well, 4GB is sufficient for your kind of usage. In fact, most apps. don't use more than 3GB of ram. While people say more RAM is always better, it is only the case when you're working with memory intensive tasks and apps., which isn't the case here.
Onto some suggestions:
-Start off by uninstalling bloatware and other programs you don't need
-Disable programs/services you don't need running at every startup
-Hard drive defragmentation maybe
-Use a program like HWMonitor to see if your CPU/GPU is overheating
-Ensure that you have a well-specc'd PSU for your system (i7 + top of the line gfx card = consumes more power)
I can't imagine anything else slowing down that hardware.
As for the SSD, while it may help with boot times and file transfers, it isn't really going to fix all your problems.
after you buy any pc (mac users should better know this too), the computer does not become impressive after a period of time
By the looks of it, I think he just got the system.
