I bought a 570 when 500 series just came out and I bought this one:

now since Skyrim and BF3 is coming out so I'm getting a 2nd card for SLI. but from my local micro center store they don't sell the ones I got anymore but this one:
http://www.evga.com/products/moreInfo.asp?pn=012-P3-1573-AR&family=GeForce 500 Series Family&sw=]

I read one of those pinned thread and I have come to conclusion that I can use this "HD" version. But what I want to know is by number everything is same and etc so what is the real difference? why does HD version cost less and so forth?

if there's no real difference I can just get HD version right now but I can wait few days of shipping if I had to order EXACT same version from the web if I must.
 
It's probably just marketing scheme.The only difference between them is one is a reference design(the one you first bought) and one is not.The reference design will exhaust the air out the back of the case while the non-refernce design will probably have better temps but it will exhaust some of the air into the case.

You should have no problem SLI'ing with them.

What are your full system specs?(PSU,CPU,RAM,etc.)
 
*I strongly suggest you do this:

Wait for the new NVidia 600 series coming Q1/Q2 2012. Sell your present card and buy one of these rather than going SLI on your present card.

NVidia claims that the cards should be as much as 3x the processing power for the same WATTAGE. That means a HUGE NOISE DIFFERENCE (trust me 2x570 is really noisy).

Also, the new cards will have a significant redesign which among other things will include much more Tesselation processing.

Overall I think you'd be much happier waiting.
