Is there a difference between CrossFire and CrossFireX in hardware?

So, a few months ago i spent a lot of money upgrading my PC, i found this motherboard on retail;

http://www.gigabyte.my/products/product-page.aspx?pid=4594#sp

So it looks good and hey, why not?

I was a NVIDIA fan but then after online research a few days later, i noticed that it's impossible to SLI on this board, and that my graphics card that i bought from the store was also not SLI capable.

Though the product site, which is identical to my motherboard, as in, it IS my motherboard, stated that it supports CrossFire, but i went to Wikipedia and searched for CrossFire, and it seems that it has different hardware versions, some that need bridging, some that only needs a good PCIe slot. Like CrossFire and CrossFireX.

So now i'm looking forward to storing my NVIDIA card and upgrading to a bigger AMD graphics card bundle, though this is the first time i'm buying an AMD card, and i don't even know what to expect in hardware performance.

So the big question is, do i need to upgrade my motherboard too for future standards?

Also, do note that there's only 2 PCIe slots, and that one is running on full x16, but the other on x4, [PCIEX16 and PCIEX4], do i also need to concern about that? In fact if they don't support cards why do they even need CrossFire support? X4 slot has been tested on a weak NVIDIA GPU and works, in fact i'm lazy to pull it out so it's just drawing more power since it's not used.

I'm currently interested to get one or two R7 series graphics cards, probably around the 260X, something like this;

http://www.amazon.com/Sapphire-Version-PCI-Express-Graphics-11222-06-20G/dp/B00HJOKCZI/ref=pd_cp_pc_0

Hey not much difference anyway right? Right?
I'm not a veteran in this, there's much to learn.

Though i'm not interested in changing my motherboard sooner or later, because i might have to reformat again since changing my old one required me to do so, and i am totally not looking forward to changing my processor, that was the single most expensive object on the receipt.

Otherwise, here's my computer specs:

G1.Sniper B5
Intel i5 4440 [LGA 1150]
Gigabyte GTX 650 OC Edition
Corsair Vengeance 1333Mhz [LP] 4GB x2
CoolerMaster 650w PSU, but forgot the full name.

That's all that's needed to know right?

Cut short edition:

Does my motherboard support current demanding CrossFire?
Do i have to concern about the PCIEX16 and PCIEX4 difference?
Is there a difference in CrossFire versions?
Do i need to upgrade my motherboard for new CrossFire versions?
Will two R7 260X graphic cards work in CrossFire?
Why did you not read the long detailed edition?
Anyone know a good game to pl... You know what, nevermind about this one.

Recommend a single GTX970:

Be aware that Crossfire isn't perfect. Some games don't support it, some do but with stutter, and AMD has not yet fixed the dropped frames issue in DX9 games.

Personally, since you want to upgrade to something much better than the GTX650 you already have I'd put my money towards a good SINGLE card like the GTX970 for about $350 ($275 if we use $335 EVGA above and subtract $60 for FC4).

Here's a benchmark to compare relative performance. Since you have an i5-4440 you shouldn't be too far off.
http://www.techpowerup.com/reviews/ASUS/GTX_970_STRIX_OC/25.html

Note that the GTX970 is almost 2X as powerful as a single HD7950. Again, remember that Crossfire isn't as as smooth or always even supported. Thus for unsupported games you're talking 50FPS vs 25FPS roughly to compare. It could even be higher than 2X in some cases with overclocking and if the game supports MFAA.

So $200 to get two, used HD7950's with Crossfire's flaws, or about $285 (subtracting free game) for a much, much better solution with all the new features it has, full Warranty, much QUIETER operation (can turn fans off) etc. ?

not to be a piss ant here but amd's CF implementation is actually really good now (it has only taken 6+ years) even better than nvidia's according to hard OCP.

in all truth if you are looking for a great buy at 1080p then even a single 7950 will get you some great performance, just make sure it is MSI so you can use your warranty. I went to CF 7950's bc i have a 1440p monitor then switched to the gtx 970 for equal performance but slightly quiterer

i did not experience any issues with CF and I have every game;)

Dammit, these prices would kill. :/

I was thinking of buying those 2 cards just to save on price, i'm not looking for enthusiast grade cards, in fact 30FPS is already good to me.
Maybe something better then 650s, but still cheaper then the ISS? Of course i'm sarcastic about the ISS part.
