I still need a mother board yet but I havent the first clue on what is compatible
we can't see your shopping cart, you should post them one by one here
for the latest GPU: PCI-E 2 or 3 doesn't matter
RAM: DD3 (the latest)
HDD: SATA 2 or 3
CPU: socket type (ex: lga 1155 the most common at this moment)
and most importantly you have to know if your PSU can handle all of this: http://extreme.outervision.com/psucalculatorlite.jsp
idk If I forgot something...
From experience I recommend Asus or Gigabyte, they're both great at making motherboards and I never had one that disappointed me.
you've got a case? I just bought this one I think it's great especially for its price and what it brings for that price: http://www.newegg.com/Product/Product.aspx?Item=N82E16811129181
(remember to buy some fans to fill the empty fan slots in the case, if you decide to buy THIS case then buy some scythe 120mm fans or coolermaster sickleflows 120mm)
I wish I could help more but I'm not an expert I'm kinda noob at this, but I think that's basically all you need to know...
