Does my pc have any problems?

Can I increase the performance of the pc without increasing the price? And will there be any bottleneck? is the power supply enough? I just want to play a graphically intense game in medium to high. Ultra would be nice though. and also, I play games like starcraft, shogun 2, and bf3. I don't want the price to increase anymore but if you can decrease the price and increase the performance that's nice,
