intel i3 2100 3.10 ghz
asus p8h67 pro
crossair 4 gb ddr3 ram
nvidia gtx 450 graphics card
how abt this configuration??????
to be honest for what you are doing that is a horrible build, but you are going in the right direction.
try something like this.
i7 2600k, with a z68 board, with a NONE gaming gpu. something in this list, http://www.newegg.com/Store/SubCategory.aspx?SubCategory=449&name=Professional-Graphics-Video-Cards.
also try to get a hyper 212+ cpu cooler to overclock with. the i7 and workstation gpu are the most important aspect of this type of build.
