Is this a good gaming computer?

For a gaming computer, you'd be better off getting an i5 2500k. It even beats the i7 990x when it comes to gaming. It's the best gaming chip available and it's such greatly priced. So you'd need a good lga 1155 p67 motherboard. It also overclocks so easily and can reach 4.5ghz on air. It'll be much cheaper and better than any i7 for gaming. Also, I like SSD's but their price doesn't justify their performance e for me. Yea you can put the OS on the ssd and shave like 8 seconds off boot time, but that isn't worth it in my opinion. Save the money and get a better video card like the 560 ti.
