Hi, I'm in a bit of a dilemma. I'm not sure which build to go with. I want to run new games smoothly, with high graphics on my 1920x1080 monitor. The build 1 is about 370$ more than build 2. If I decide to buy the first one I will OC if not I wont. Also, if you think there's a bottleneck, or something I need to change please let me know. Thanks in advance.
