I mean if you have the stuff already, you're going to have to live with the bottleneck.
Think of it this way. If you had a Radeon HD7990 with your Pentium, it would still perform better than the R9 270X. People seem to obsess over these "bottlenecks" to be honest. A balanced system is nice, but one that isnt isnt like the end of the world.
Basically if your computer performs how you like, I wouldnt change a thing.
Just give it a try I would say probably but cant be sure because I never tried it. If you have not yet purchased the cpu you should consider going with a i3 or something like that if you are on a budget.
