Trevorwilliams23 :
I guess I messed this up pretty bad. Thanks for your guys help and I'm sorry about this. I have a couple parts picked out but I'm not sure about others. My budget is $2000
GPU-780ti
CPU- Intel i7 4771
Motherboard-Intel® Desktop Board DH87MC
Case- Cooler Master Haf X w/ SuperSpeed USB 3.0
HDD- 1tb WD Velociraptor
I'm not sure what to choose for the ram, power supply and optical drive
Also how do I tell if these all work together? Do I need anything else? Do I need a sound card? Should I trade anything out? And should I get a small ssd for booting?
Thanks for your help
Here I stuck your build into pc parts picker

I changed your HDD to a seagate barracuda 1tb, its cheaper than the velociraptor and just as good.
I added a 750 W power supply from seasonic. pretty much all of seasonics psus are good.
I did add an SSD boot drive. Trust me its worth the investment as windows will boot to desktop within 15 secs. Also its not really prone to the same problems that HDDs face.
I changed your cpu to an i5 4670k. It gives you the potential to OC later, and it won't bottleneck your gpu. Most games are reliant on your GPU so the CPU doesn't affect gameplay that much. It also saves you a $100
You don't need a sound card as the built in audio in your mobo is good enough nowadays
BTW what games are you planning on playing bc a 780 ti is really overkill. You could get by with a gtx 770
You could swap in a radeon r9 290x and save yourself some money if you really want a gpu of that caliber.
