Question from JHall14 : "1080ti i7 7700k build for $1900 worth it?"
JHall14 :
On ibuypower I can build a computer with a 1080ti i7 7700k 16gb ddr4 2400 and other things. Is it worth it if I get a computer with that for $1900?
Hard to say.
You'll most certainly need to replace the PSU.
DDR4 2400 is pretty slow by todays standards, you should easily be able to get 3200 with 14 or 15 CAS/CL
How is the storage?
Because of the fact that you'll need to spend money to get up to spec - it is almost always better to build your own. The only place you're saving decent money is the Operating System, but on a build of this caliber that small OS cost doesn't offset the cost of the PSU, RAM, and storage.
