Will my CPU bottleneck a new Nvidia 1070?

[Specter0420]

I have an i7 920 overclocked to 3.6 Ghz. I can (and have) push the OC up to 3.8 and suspect I may be able to reach 4 Ghz. The i7 920 has 4 cores with HT for 8 threads and I have 6 GBs of DDR3. I plan on upgrading that too. I plan on getting a 1070. Should I upgrade my mobo, ram, and cpu or just get more ram and a 1070? Another option is to upgrade my processor to a xeon 5650 (six cores and 12 threads) for like $60 and overclock that.

What would you guys recommend. I plan to get a Rift CV1 and play mostly flight sims. So should I;

1. get a 1070 and some ram, push my overclock?
2. get a 1070, ram, and the xeon, then overclock?
3. get a 1070, new ram, new mobo, and new cpu?

Thanks!

honestly if you have the money option 3 is going to be your best choice, your CPU while able to handle the 1070 without a bottleneck its fairly old hop on the skylake bandwaggen. but if you want to save money honestly just get 16gb of ram 4x4gb or 2x8gb is best and don't worry about overclocking your I7 more its unnecessary with this option be care that you are obviously using old hardware.
