I have a few dumb questions I need your expertise with...

#1
"Intel states Memory Specifications"
Max Memory Size (dependent on memory type) 32 GB
Memory Types DDR3-1066/1333
# of Memory Channels 2
Max Memory Bandwidth 21 GB/s
So can I use Kingston HyperX Blu 16GB (4x4GB) 1600MHz DDR3 CL9 DIMMs, w/XMP? Or should I get the DDR3 1333 PC3-10600+ rated stuff? The motherboard says I can use the following Dual-Channel DDR3 2133/1866/1600/1333/1066 MHz? thoughts?

#2
And will the stock cooler master 500Watt PSU be enough to run my setup safely? Should I upgrade and is that 500watts enough juice to power my build?

#3
Will this video card be able to power this Acer H274HL 27" Monitor in the HD mode? (HDMI connection wise?)


Thanks for your help in advance.
