Dude if you are going to spend 280 on that card upgrade your system atleast. I don't know exactly what you have but I can tell you just from that picture that your mobo and CPU are going to bottleneck that card.
because the video card is the most vital piece when playing games.. 280 might be a little much for my blood nowadays, but when building a new system, that seems about right, even if the system is built piece by piece.
