First of all im not much of a AMD guy so i can't help you with the processor but i've heard that this processor is pretty good. Next, i would go with the Corsair because the extra MHz only makes a differance if you were using a APU because the APU would be using that memory. For the Motherboard it depends on what features you want with it. Lastly, the NZXT will work just fine.
Vengeance ram has silly over sized heat spreaders thay will stop you adding good heatsincks on the mobo (you will whant one as the AMD stock fans are loud)
The asus mobo is the best for the money it has sata iii 6gb/s a usb 3.0 header a good vrm (all be it a 4+2 but still solid and you can overclock on it) it allso has a heatsink on the vrm's to keep them cool
High high quality components + it is bios supported out the box for the FX6300 (R.20 are all refeshed vershons ready for all FX cpu's)
If you what to grab a NZXT source case get the 'elite' vershon as it has usb 3.0 on the frount of the case so you can use the usb 3.0 header on the mobo.
The Asus is a little high priced. im not shure about sata or what it is. Im not shure if im gonna use all the stuff on the asus. i took ur opion on the ram and will go with the hyperX but i am not shure what u mean buy the stock amd fans? is there an easyer way to message u like through pm. i am going to buy the parts tomoro
Serial ATA (sata) is used to conect your harddrives/ssd's/dvd/cd player's to the motherboard.
sata iii 6gb/s is newer and twice as fast as sata ii 3gb/s.
Cpu's ship with a stock heatsink/fan to cool the cpu but the amd ones are terribly small makeing them very loud (AMD realy expects you to add a better one your self as 9 times out of 10 AMD chips are owend for overclocking)
Will the sata III fit all harddrives/ssd's/dvd/cd and i dont play to over clock my CPU but is it somthing i should look into and is it worth to spend $20/30 to buy a heat sink?
so i was talking to another guy and he says that i should go with this setup: http://pcpartpicker.com/p/1mAoz its barly fits my price range and it looks good. whats ur opion. should i buy?
MSI in my experience is a bad brand, I've had problems with every single board from them, and its not just me either
Asus however kicks ass, they have awesome quality Assurance too so you know its highly unlikely you'll recieve DOA or your stuff crapping out 2 days after the warrenty expires
There is the Asus M5A97 R2.0 ATX AM3+ (LE vershon ) its a nerfed M5A97 R2.0 it lacks a usb 3.0 header and the vrm's/mosfets dont have any heat sinks its about $75
