An x4 slot is normally for a dedicated PhysX GPU or any other PCIEx16 card you may want to add.
ugh... significance lol? does it mean my gpu goes here? Is x4 not good enough?
It has two PCIEx16 slots. One runs at x16 and is for your GPU. The other is x4 and can be used for a secondary PhysX GPU or some other expansion card (Ramdisk maybe) that you might add in the future. Its not very good for crossfiring two GPUS.
So if i don't plan on cross firing is the motherboard still good?

I have an MSI board- P45 Platinum. It's great, but I had to hunt down a beta bios v.1.7 for that to be true. Also, they are a chinese company and the support is only so/so and the manuals are pisspoor and barely readable.
hardwarewise, it's a good board. Update the bios, mine shipped with 1.4....
