Ok, so DDR3 1866 is preferred. That helps narrow down gigbytes supported list by more than half (only 22 choices of 1866 vs. 57 for 1600). Are any of these manufacturer's better than the other (Avexir, Corsair, Crucial, Geil, G.Skill, Kingston, Patriot, Panram, Silicon Power, Team)?
be aware KOOL that most likely you will have to oc your system to get speeds on ram like 1600 or above. but dont be afraid of it, it's not that big of a deal to do it.
but if your ram is on the list it's most likely to not cause a problem. I have ram that isnt on the list for my mobo as the list was very limited and I have never had a problem with it. but some others did with with the exact ram on the same mobo. go figure.
I like gskill, just because this is my second build and never had a problem with it, except once. and that was due to a bios update where they mobo manu messed up and you could only use one stick but that was promptly fixed.
if I was you, and I was going to reuse parts from my old build. I would get the mobo/cpu/ram first. reuse the case, hd, dvd, ps and os. If I recall correctly you built your other one too. and add parts or more better parts as your budget allows.
if you need a sound card, i have 2 available for the price of little more than shipping. one is brand new that I just didnt have the time to return and the other is the sb z series. a better card with great sound.
