I think i am a bit confused between the R9 270x and the HD 7870, yes i do know the R9 270x is faster and is a more recent card but the thing is on Newegg.com it is also $50 more expensive than the HD 7870. I think what i would like advice on is if the extra $50 is worth it for the performance increase. I also do understand that the R9 270x is just a re-badged HD 7870 with a few tweaks and changes on it. Do you think the minor changes and tweaks are worth $50 more? Any advice is much appreciated.

He is right, a 270x tends to be closer to a 7950 since most come factory overclocked. I would go for the 7870 and try to overclock if you are comfortable with it.
To give you an idea
Cheap 7870= Pitcarin GPU running at 1000Mhz
Cheap 270x= Pitcarin GPU running 1050
Good 270x= Pitcarin@1150-1200
Cheap 270 non-x= Pitcarin at something like 950-1000Mhz
