Need to upgrade my motherboard for SLI

[pointflow]

Hi. I'm looking to upgrade my motherboard so I'd be able to run my two 550 GTX Ti graphics cards. My current motherboard doesn't have enough room or PCI-E slots. I figured since I don't know anything about motherboards and have no experience with SLI, I should ask here.
I have the two graphics cards already, got two-for-one on a mad sale, but only have one installed (because of my motherboard).

My processor is an Intel Core i5 CPU 760 @ 2.8 GHz

Not sure what other information you need... Let me know.

The i5-760 cpu need the LGA1156 motherboard. In newegg.com you can see there are only two of them, I don't where you are and you can find some from amazon too. But the point is that it is the old one and you are better to save more $$, and use the $$ to buy the 7 series motherboard (B75) +3rd Generation CPU ( i5-3XXX). Because when intel will release latest-generation processor code-named Haswell on March this year, then maybe there is the sale for the CPU/MB you can buy.

Thanks for the reply. I used a program called CPU-Z to find what motherboard I currently have.

So it's not exactly the best...
Do I absolutely need to upgrade my processor or is it just recommended that I do?
Well, I'm in the UK, and on Amazon I can get the LGA1156 motherboard for around £60.
The thing is, I don't know anything about motherboards so I'm worried that my current hardware won't be compatible with the motherboard, or whether everything will fit on the motherboard, since the graphics cards are dual width. I don't even know if the motherboard will fit or if I'd need a new PC case.
My RAM is dual-channel DDR3 by the way.
Thanks for the help.

EDIT:
What if I get these two?

Those two are compatible, I think. Is there a way to check if my RAM and everything else would work with it or is it not as complicated as that? Any recommendations for a cooling system or do I not need one?
Edit again:
Here's my PSU box for reference:

I'm really sorry for throwing all of this information and these questions at you, I'm just trying to help give a better understanding of what I've got just now, and I'm not expecting you to know everything.

If you want SLI, you need two of PCIe 2.0 X16 or PCIe 2.0 x8/X8, or x8/x4 (as same as PCIe 3.0). Go to amazon.co.uk I found the one for around £60 that has the only one PCIe2.0 x16, so that you can't SLI. THe RAM on your MB is the DDR3 RAM so they can use on the most MB like LGA 1156, or the one (z77) you list .

The new i5 and the Z77 wil be the best combination for the game, If you have tight budget then you can go the non-K CPU with H77/B75 motherboard too.

For the PSU I can't find any info about it, maybe only use in the Europe. The PSU is the heart of PC so you need buy the good PSU as you can . you can check the link for Who's Who In Power Supplies, 2013: Brands Vs. Manufacturers: http://www.tomshardware.com/reviews/power-supply-oem-manufacturer,2913.html

Back to the topic, i5-760 is still good CPU but you hard to find the MB for you do the SLI. If you want to cool your CPU, you need the CPU cooler like Zalman CNPS10X Optima Ultra Quiet Intel AMD CPU Cooler + Arctic Silver 5 3.5g Thermal Paste.

I think I'll go for the new i5 and the Z77 motherboard then, since both have good reviews. I may as well spend more money for a better product that will last longer, and the motherboard (the Z77) has everything I need I think.
Yeah, I can't find much about the PSU box, I'm just wondering if it has enough power to support everything I'll be installing since I'm not sure how much more power SLI will require.
Thanks for the links, do you recommend that CPU cooler? It has a good price.

Thanks very much for all the help and info.

From one review 550Ti SLI, they need ~420W. Keep the eye on the PSU now. I don't know what game you play, if you play like BF3 then you need upgrade the GPU or PSU too. http://www.neoseeker.com/Articles/Hardware/Roundups/nvidia_gtx_550_ti_palit_msi/18.html

Go for a intel Z77 series, ive got the DZ77GA-70K and its amazing and it works SLI

Yeah, that looks amazing. The thing is it's a lot more expensive than the motherboard I was thinking of getting (AsRock Z77 Extreme4), but I might save up for the Intel one if it's worth it!
