While I am new to the whole pc gaming community I have been eye balling some pre-builds on newegg to start with and slowly upgrade over time to get my feet wet in the whole process of eventually being able to one day just build my own. The problem I'm running into is understanding the b75 mobo they have listed on many of there machines say they only have 1 pcie 16x slot while this one,( http://www.newegg.com/Product/Product.aspx?Item=N82E16883229388 ) is listed as having two. Could that be a typo or are there different versions of that model mobo? My main concern for having a 16x pcie slot is eventually to be able to use crossfire/sli.
