It fully depends on your situation, which we know zero about.
Do you have a competent GPU, but just have a desire for something more? Then probably no, because new GPUs are coming in the fall and they are looking like a bigger leap than previous ones.
You don't have a GPU and absolutely need one? Then it depends on if missing out on something is more important than using that kind of money to something that is probably worth 1/4th in 4 months.
