To start I know absolutely nothing about motherboards, so feel free to speak dumb to me.
I have recently starting using my PC for trading and streaming and I plan to make some upgrades in the near future.
Currently I have:
I5-7400 @ 3.00Ghz (4 CPUs)
GTX 1060 6GB
16GB DDR4 RAM
AsusTek PRIME B250M-A (Motherboard)
I plan to upgrade to one of the CPU to one of the I9 series but I am not sure which, as well I plan to upgrade the GPU to either a 2070 super or 2080/2080 super. The one thing which I need while trading is triple monitor support from HDMI so I can manage graphs, spreadsheets, etc and I know AORUS has a few I have been eyeing.
The main question being that I know for fact I have to upgrade my power supply being it is at 500W right now, however though should I upgrade the motherboard and what would be the downsides of putting either an I9 9900K/9900KS into my existing motherboard. Please recommend some motherboard choices >$300 CAD.
On the other hand if I am upgrading the motherboard should I just go all out and rebuild my entire rig?
