Extreme Memory profile is a feature that allows you to quickly setup the rated timings of your RAM within the BIOS. Since when you install new RAM in a motherboard it always sets it to some default safe settings which are slower than the rated settings. You need to go into the BIOS and adjust the memory multiplier and timings so they match what they are rated for. XMP will save you about 2 mins on the initial setup and is nice to have if you aren't too comfortable changing stuff in the BIOS (though you still need to go into the BIOS to turn on XMP).
The vengeance memory is nice and XMP is useful, but it has some really annoyingly large heatsinks which will reduce your options for CPU coolers if you decide to overclock, therefore I wouldn't recommend going for it.
well im not to confident with bios settings and suchlike but im sure all the advice i need is right here on the forum, and its good to learn these things, so i'll probably go for the ram you suggested.
so finally onto the graphics card how does the card you suggested bare up against similar priced nvidia cards? is it all about amd cards these days when comparing to the same sort of price of nvidia cards
Sorry to turn this thread into a build thread by the way
