This build is by far my best. Cost me $3500 to build. In the end all new parts. The only few hiccups I had were my 360mm fan placement for cpu cooler and Bios needed updating due to freezes. I also tried to save $200 and buy an open box video card. Well it went right back and I'm now $200 lighter. could have saved some aggravation if I had just bought new the first time. In any event, my bench marks are through the roof! Gamming has never been so fun!
