You don't need M2 to get a faster SSD, there are PCIe SSDs out there,
although they are more pricey than SATA ones. M2 can be a bit
confusing, as there are several different form factors. I don't know if
one is more common than the others yet. Samsung in general makes good
SSDs, but they have had a couple of high-profile firmware bugs recently
on some of their drives. I think they have been fixed by now, but check
before you buy.

If you are buying a new CPU and motherboard, make sure that your CPU
has a suitable number of PCIe lanes for your needs - both M2 and PCIe
SSDs eat up several lanes, AFAIK. If you also have a heavy duty
graphics card (or two), it all adds up.

I'd also advice you to get a quality, reliable power supply. Spend
money on a good one, don't go cheap. The one in my desktop is a Corsair,
and I'm very happy with it. Even if you don't use a power hungry CPU and
graphics card, clean, stable power is a Good Thing. A bad power supply
can destroy hardware, and/or make it behave in strange and unpredictable

Just my 2c :)
