@KrinkinOnline: what's exactly poor about the rig I posted? Mine has a faster CPU and a faster graphics card (HD7750 is more or less equivalent to HD6770).
Here is a comparison between i3-2100 and FX8150: http://www.anandtech.com/bench/Product/289?vs=434
i3 wins in Dawn of War II, Dragon Age Origins (slightly), and WoW. FX8150 is better in StarCraftII, but just barely. And FX4100 will definitely perform worse than FX8150, since it's not a true quad core CPU. It has two modules, each consisting od 1 FPU and 2 ALU (not 2 FPU and 2 ALU).
FX4100 might catch up with i3 after OCing, but power consumption will be much higher.
