New motherboard opinion?

[TechMiller]

So I have an old setup, and recently got a newer video card. I am wanting to upgrade to a PCI-3 from the 2. The question I have is, how much more performance will I get going with a new CPU as well or just getting a newer board that still fits my older CPU.

This is what I have.

ASUS P8P67 DELUXE (REV 3.0) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS

Intel Core i7-2600K Sandy Bridge Quad-Core 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W BX80623I72600K Desktop Processor

XFX Radeon R9 280X R9-280X-TDFD 3GB 384-Bit GDDR5 PCI Express 3.0 x16 CrossFireX Support Double Dissipation Edition Video Card

I see that they still make 1155 slot boards with PCI-3 Would I be wasting money to go this route or should I just save money and go with a newer CPU as well. (I don't really have the budget for this option)

Thanks for any help!

Upgrading that CPU is a waste of money. Still competes closely with the i7 4790k and i7 6700k. Also PCIe 2.0 won't bottleneck your GPU at all. Some site (don't remember what it was), but they did a benchmark testing different PCIe versions and bandwidths (x16, x8, etc) and PCIe 2.0 was only like 2 fps slower than PCIe 3.0 with a GTX Titan.
