I would go for Windows 7.

You'll still be able to upgrade to Windows 10 on release, so I don't see a reason for why you'd opt to use a ridiculously streamlined OS, that ended up being difficult to use 😛

You can get Windows 8.1 and install classicshell, if Dx 11.2 matters to you, amongst a few other features.

Definitely 8.1 if you're going to run multi-threaded apps and games.

I prefer Win7 as well. Less bloat, more stability. And maybe a little more performance in games (which is all I use Windows for anyways).

But Win7 is already End Of Life - no more new updates (aside from the most dire new security vulnerabilities maybe being fixed), no more official support. It's also getting hard to find (and a little more expensive) on store shelves, once they sell their existing stock it's gone.

So you might be forced to use Win8.x anyhow. Not so bad, really, since it supports a few newer technologies (including newer DirectX capabilities) which older Win7 lacks.

Win10 is just around the corner. Most people using the OS beta (aka Windows Technical Preview) seem happy with it. Apparently the less popular Win8 GUI elements/styling can be deactivated for those who prefer Win7's more sedate functionality.

Actually, the W8 Metro has been entirely removed.

Graphic is still not like Aero Glass, and more like the W8 graphic, but the metro is very similar to the W7 Metro, except with a small subcategory that is similar to the complete W8 Metro, but designed in a more XP *all programs* way. Not sure how to describe it 😛

All programs functions the same way as the W7 Metro.

It's basically the modern features of W8, but it runs better, looks better, and is a helluva lot more useable.

Thanks for all the information. was worried about MB and RAM compatibility

Yeah, don't worry. It's going to work fine.

Enjoy the new toys :cool:
