What are the specs of your dead system? Maybe it'll be worth some time trying to get it back up and running. It's incredibly rare for an entire system to give up in one go and sometimes it's something silly like a loose connection or blown fuse.
It all depends on how much you want to spend, what type of games you want to play, what detail/resolution do you want to play at, how long are you planning to keep the system, etc...

If your pc died, it is a good time to build.
What will you do in the interim?
What is your budget?
Initially, the GTX1180 will be the first released product.
Expect it to be in short supply and considerably more expensive than the current top dog the GTX1080ti.
Depending on what your existing system is like, if it's not too outdated I would look into fixing and upgrading that.
The 1180 will likely be getting announced at Nvidia's big event in a little over two weeks, and should be available for purchase sometime thereafter. There are no confirmed details on what pricing or performance will be like though.
