I am a hardcore gamer but have no idea about anything with building a good computer. I pretty much want to play SWTOR and other PC games at high or ultra with great fps(preferably over 30). Right now, my current computer isn't getting anywhere near that and I want to upgrade my graphics card to give me that boost. I got sent to this one in particular (NVIDIA geForce GTX 560) or the link below. I just basically wanted to know if that is something I should get as it will be a good upgrade and if my current specs will run this graphics card or if I will also need to upgrade anything else.
All help would be greatly appreciated.
