I want to upgrade from my current PC which is very slow and can barely even play games like TF2 without lagging every few seconds. I'd like to keep it at about $500, without going over by much. I'm not looking for a huge powerhouse PC or anything, but I like to be able to play games like Garry's Mod at high settings, and have medium-low setting on games like BF4 and Arma 3 with a stable 60fps or higher.
The only PC I've found in this price range with a lot of power is the CyberpowerPC Gamer Ultra 2098 (GU2098) which can be found at: http://www.newegg.com/Product/Product.aspx?Item=N82E16883229285&cm_re=cyberpowerpc-_-83-229-285-_-Product
It is $509, but there are many different reviews about it. Some say that it can run BF4 on medium-high setting very well and other say that it struggles to play at low.
