Is your current setup spoilt? If not, don't see the need for you to upgrade leh.

Asus z87 pro
Intel 4670 processor

You don't even need a wifi card, motherboard has it. Also has Bluetooth

But yeah IMO you will be better served spending on a better monitor

Like no need to upgrade le, unless u suspect ur MB dying off.

The board PCIe x1 is block by GPU.
Cant plug in wireless adapter, USB wireless is cui due to wall, distance & interference.

May be I should just get a 2nd hand mobo and wait a bit longer before upgrading sometimes later?
