I have recently completed this build and I really like it. I'm hoping to upgrade to a core i5 and 8 gigabytes more ram as well as another video card to run crossfire. But this build is working great for me. Anyway I have tried running a few games on it and they run with acceptable fps on high settings, one game I have tried is Payday 2 and it runs smooth and looks great with this build.
This cpu works great for most games and the hyper threading is a great bouns which gives you four threads.
This motherboard is a great micro Atx motherboard it has two pci express ports for future upgradability, as well as four ram slots, and finally because it has three 6 gigabyte sata connecters.
This ram is great for a budget build because of its price but later on you might want to add another stick just to run games nowadays.
This is the best budget harddrive you can buy, there is no other choice in my opinion.
This is a perfect graphics card for this build because you can overclock it, which gives extra performance and because of its cheap price point its great. As an added bonus it has two gigabytes of gddr5 memory.
This case is absolutely fantastic its easy to work in, and is pretty quiet, also it has great cable management on the inside for better airflow which is especially important for a small case like this. Finally its great price for less then $50 makes it great for this build.
This power supply is definitely enough for this build and provides some space to upgrade in the future. The semi modular cables also help because you don't need to install them all in this build which helps with air flow.
