MSI Z77A-GD65 or asrock z77 extreme4

Depends on your uses. The MSI has more features, but you shouldn't buy the board unless you know you need three PCI-e slots or any other feature the board has.

The AsRock has PCI slots (while the MSI doesn't) so if you need a PCI slot then get the AsRock.

Basically, unless you know why you're paying more for the MSI board then don't buy it.

If I were you I would get either the ASUS P8Z77-V or the Asus P8Z77-V LK. Again the more expensive board has more features and will be better for overclocking, but only get the more expensive one if you know you will need the extra features.

asrock hands down

oh and pci slots are the used for things such as hard drive graphics card and whats that thing called where it tells you the temperature of your computer???

i heard that the asrock is an inch smaller how would i put it in my case if its an inch smaller?

haven't seen anyone have a problem fitting it in their case and i believe the program you are looking for is Core Temp
