Yes - I checked that the BIOS supported nVME boot first. I'm using an Asus Sabertooth Z97 based MB
If you already have a Sata based SSD; I wouldn't get too excited about upgrading as the perceivable performance difference was very small. If you have expectations set on all the impressive sequential RW scores then be prepared for a huge disappointment. My understanding is that random RW performance/IOPs is much more important for your boot drive and nVME doesn't necessarily offer a huge leap on this front (with the caveat that many manufacturers do put their best stuff into nVME anyway) - it can be worse as well.
This can't really be stated enough, I even posted a thread about that very thing. Particularly with more complex games and compressed loading times, nVME is down to single digits percentages difference from SATA SSD, and in some cases is even slightly worse (I put this down to the better SATA SSD models having pretty robust processors to help with I/O, vs most nVME being much simpler in design and more reliant on the CPU via PCIe lanes to handle the I/O load more fully, or in the case of controllerless NAND SSDs, *FULLY* passing the buck so to speak over to your CPU).
They are convenient. For the better models, the performance is certainly better IF you can feed it enough to work from (this will get more relevant in an all-solid-state world in the future) efficiently.
Gamers probably make the least likely market to benefit from them though, as loading speed differences are basically indistinguishable.
Caveat here is that many desktop PCs are ideally suited to no more than one PCIe x4 SSD, as Intel s115x only has 16 PCIe lanes native to CPU access. If you have a pair or three PCIe SSDs, the performance potential when combined with a PCIe x16 GPU is marginalized somewhat, increasing bottlenecks and raising CPU I/O overhead. It's for reasons exactly like this that Zen platforms as well as Intel HEDT have many more PCIe lanes, which can make running multiple PCIe drives and 10Gbit Ethernet much more efficient.
