Lol I saw that before. Not worth the price. Build your own. Get an i5 and 8gb of ram. Make sure to get a powersupply that has enough watts for the build and do not get a standard power supply. Also for gaming a gtx 670+ or 7950 or 7970 will be great. The performance isn't too different beween the 7950 and 7970.
Just do your research and watch some tutorials. I don't think it is that hard.
