i think for the psu 750w will be enough but it is good to do
your own research
for mobo, get evga, no doubt about it
can choose from a few models, got V55, P55 and other variations
of the P55 depending on your budget
what i like about evga is the ability to oc the processor
easily(especially for noobs like us) and they provide excellent
customer service support (evga staff even creates guides on how to
oc particular mobos at the evga forums, HOW COOL IS THAT!)
north south east west that one idk, ask raraken heh!
1156 got H55, P55, H57, Q55 and Q57. Go for P55.
I would suggest East West orientation, with the cooler fans
exhausting the hot air to the rear case fan. It will intake cool
air over the RAM modules as well, so that's a plus.
Not overclocking that much, go for MSI.Good warranties and
qualities, at a good, cheap price, as well as one of the best
distributors in SG (Corbell).
