Oh sorry for the mistake, post edited@OP: Its primeabgb. Not primeagbp like sunny said.
Also stay away from theitdepot. No matter what, dont ever order from them. They overprice, delay, and never update you about the status of your order. Its like throwing your money out of the window.
Not buying the stuff online. Just want a reliable place to check prices.
If it is DDR3, it will work with out any problems.
Do you mean frequency, timing, voltage etc. does not matter as long as I have DDR3?
Additional features is what brings the difference in prices. The Deluxe version has 2 NICs and things like that for the other boards. Just compare them yourself to see if you are able to find the differences.
^^Nice build, bought it?
