Need clarification so I can buy these parts.

[heavymetal2000]

So I've narrowed down my list and I'm ready to buy.

I've got an incompatibility issue regarding b350 board and my 2600 cpu.
Is this still an issue? Will I need another chip to update my bios or is this solved now days?

The m.2 slot is directly below the gpu slot, will this cause heat issues with my current selections? The gpu has a back plate if that helps at all.

Is that PSU good enough to handle a mild cpu overclock and gaming?

Can anyone see any issues with this?
I'd like to place my order today to take advantage of these deals now if possible.

Thanks for any help!

There are a lot of people on here every day that can't boot it on a b350 board avoid the headache and get a b450.

That is a solid psu

Thoughts regarding
Msi b450m gaming plus vs. Gigabyte b450m Aorus vs Asus tuf b450m plus gaming?

All are with 5$ of each other atm but there all like 45$ more then the one I have on the list.

I personally always choose Asus unless something solid is drastically on sale when I go to buy

I decided on the Asus as well after reading up on all 3.
It's definitely an upgrade over the original 350 I had picked.
