I have these components. I know this system is old but it should play at least at low settings unless there is something wrong!
Concept of bottleneck is also new to me so enlighten me in anyway so I can peacefully play tomb raider or metro on LOWEST settings.

I am ordering COOLER MASTER Hyper 212 EVO
Any upgrade suggestion would be appreciated too if there is no problem with the system!
Thank you for your time.

On metro pc on lowest setting, I cannot even do benchmark with more than 3fps....
Oh and I might add my temperature on cpu are soaring 90c with gaming but I doubt that can be only reason
Oh and on side note I used to play lot of games including Assassin's creed except 3, Skyrim on ultra without mods.
But now that you mentioned integrated gpu! Is there anyway to disable it or it does it automatically when I inserted 560ti 2 years ago? It just worked fine before so what is the problem now? ><
