Hey guys, so I've been messing around with pcpartpicker for a couple of hours and just can't seem to find the best possible parts to pick for my gaming rig. Can you guys help me out? I unfortunately forgot to save my parts list but I would really like to have an i7 4790k quad core, two-way sli 980ti's, a 2TB HDD and a decent SSD. I just have trouble picking the right motherboard and finding parts that are available to purchase online. I am trying to keep it under $4000 and would like for it to be air cooled. Any help is greatly appreciated.
