Will I Be Able To Run It

[IamAzura]

Hey Guys I'm New Here, Well my question is quite a Newby Question.
So I bought this setup Ready Built and from what I know I think it has 500w PSU ATI Radeon HD 5450 Gigabyte M68MT-S2 MOBO and 8GB RAM also Has 1TB HDD so my question I put to you is my specs are obviously not strong enough to butt hurt on any new games like black ops 2 for example I get 25fps on low setting everything low and 800x600 I think so my question is what the best and easiest way to upgrade my graphics card also I'm only 16 and I'm sure you can understand its hard to spot cash nowadays So thanks for reading and please help

I am going to hope it at least has a Phenom II in it ... though need you to confirm what your CPU is.

Without knowing your CPU, my vote for GPU is 7850. Minimum 500w PSU and a good mid-range card.
