Hey guys,

I've looked through a bunch of similar threads over here, and I think I have the picture on what I want. Just wanted to triplecheck before to commiting to the SSD I'm interested in.

I'm currently using a Gigabyte z97x Gaming 5 mobo, with a Gigabyte R9 290x OC on the PCIe x16 socket. I'm looking to add one of these to my system:

Judging from previous threads, and looking at the mobo block diagram, if I place the SSD on either the M.2 slot or the PCIe x4, it should run off the chipset, so it should not have anything to do with the PCIe x18 running off the CPU.

1st question: did I get that right?

2nd question: as far as I can tell, the M.2 on my mobo is PCIe x2, so the MP500 would not run at full performance. I'm mostly interested in gaming on my machine, so is it worth getting an adapter and placing the SSD in the PCIe x4? I feel like the difference wouldn't be observable, but who knows.

3rd question: if I should go for the adapter, what exactly am I looking for? Is something like this any good?

Sorry if this thread seems redundant, and thanks :).

Solution
1st: correct, from the chipset

2nd: you won´t recognize a difference ingame

be sure your motherboard´s BIOS is updated before installing the SSD. Use Q-flash in BIOS itself, don´t flash in windows.
