hi, i'm looking to build a pc for mainly music production (running cubase) but also for some gaming
I'd like to be able to overclock the cpu to at least 3.4Ghz. does the below spec look like it would all work together? I know the case is a little overkill but at some point I would like to watercool the system so I went for a huge case - plus it looks cool 
One thing i'm not too sure about is a cpu cooler - could somebody recommend one?
Lastly, i believe there is a price cut on the processors on the 16th october? Any idea how much this will be, coz if its a matter of £10-20 I don't think i'll bother waiting. Am upgrading from an amd 4400+ so am hoping for a big increase in speed!
