Gigabyte GA-Z77-D3H vs GIGABYTE GA-Z77X-D3H, is't worth it?

[RiskYourBuild]

Hey, first, this is my first post here.
Second, is why this post is made; Today, I bought a PC, I didn't build it myself, I paid a shop and they offered me free building because I bought all the parts from there, so I went for it.
Well, I ordered it to come with a Gigabyte GA-Z77-D3H, but now I'm wondering, that it should have been better if I went with the GA-Z77X-D3H, is there any performance boost? I'm not sure if I can give the store the extra money and tell them to change the PC, so, what I'm asking for is should I call the store and ask them to change and give them extra $30 or so? What features are different? Does the GA-Z77-D3H support Crossfire (I went with a 7950).
Thanks in advance, hope I will get answered fast, and I really want a detailed answer!
Really hope my journey with this site will be a happy one!

No performance boost. Here are the specs. http://www.gigabyte.com/products/comparison/list.aspx?ck=2&pids=4327,4325

Thanks, is't worth it to change SSD from Corsair Force 3 to Crucial M4 as I see that the M4 is better in almost every benchmark?

Go with Crucial M4 or a Samsung 830 or 840. I have a Crucial M4 in one system, and a Samsung 840 in another with no problems yet. Just make sure the firmware is the latest for the Crucial ssd.
