all garbage except for bees
one of the most respected friends did not mention at all about the memory
if you attend to the possibility of an upgrade, you will suddenly discover that there is little choice
here's the deal: trudnostyami and most useful in a computer is the memory
first, determine how much you need: 32, 64 or maybe 128. Even if not now but in the future.
then imagine that after a year the memory blocks will be different - ie, now is not the channel to put DDR3, and to take such motherboards in a couple of years to upgrade this memory will stand dooroge percent or postergado laptop
this place will disappear half or all of the above you sockets
after determining the memory under it, choose percent. Then suddenly find that for many i(7-5-3) - 64GB - ceiling but Xeon. But maybe you do not need so many.
selecting percent - look at his motherboard. More SATA3 connectors, maybe SAS will find (there are, if necessary, of course), or is there a 2-3-4 PCI slots if you are a gamer. Well, all the same support for your memory - then the motherboard can also be not up to par - 32 max - the normal phenomenon, generally 1-2 128, 64 is also a small selection, but there is.
