Default Enable jumbo frames

Will soon get my new 8-port GB-switch, and from what I've heard without jumbo frames you dont notice THAT much of a difference.

I guess its best if all devices on the same subnet use the exact same MTU-setting for the frames...right? Jumbo frames ain't something magical, its just the ability to set a higher MTU-value....right again?

So, had a look in Vista and I can set as highest 7KB MTU (6KB 5KB 4KB....).
I guess that doesn't mean 7000 byte, but rather 7168 bytes???

So, do I just run "ifconfig vr0 mtu 7168" on my OpenBSD and thats it?
How do I even know 7168 is a supported size on that NIC?
My Vista machine didn't go higher than that for example, maybe others just go to 6KB or 5KB or....???

What will happen if the values dont match correctly, is it just bad performance or will I loose connection to my BSD-server until all partys have the exact same value entered?

Might have the BSD-machine on its own subnet (either VLAN or a totally separate interface and then jumbo frames wont do any good I guess, through the router, but I'll see how I'll set it up).

Thanks
