1. I know the sockets not new I picked it for performance as the haswells are too expensive for too little extra performance. Also I won't get much power savings which is haswells main addtion and selling point from buying a vastly more expensive quality mobo.
Haswell has a lot of under the hood features that isn't just power savings and such. Things like TSX and whatnot might be useful to you if you're doing IT/server related things. Don't just look at the surface, dig deep.
3. i do want the 16gb of ram partly for performance and partly for other applications i use like windows own xp mode.
More RAM only equals performance if you're running out of it. Having more RAM than you need doesn't improve performance at all. It just may make things more snappier because less things are being swapped.
4. i want windows 7 pro because of the admin functions i am in IT by trade and home will be crippling for familiarizing myself with the administrative and network stuff I need to know.
Well it depends on what you really need and if there are alternatives for them. XP Mode? Virtual box with a copy of XP. Remote view? TeamViewer or Hamachi. Encryption? If you don't need the OS encrypted, TrueCrypt will work just fine.
5. SSDs are too costly atm [a decent 120+gb costs more than a 2tb HDD and costs more than my motherboard] and are planned for future expansion. the caching idea works on 150 mobos too it's windows that causes people problems doing it. I plan to add an SSD later but figure a HDD will be fine to start. I plan to relegate the 1TB HDD after to data storage and back up etc.
Just be aware that the longer you wait to do this, the more painful it might be to do a migration without a wipe.
6. The 750w power supply partly is to account for the overclocked graphics card and future additions which can include more fans and hard drives without me having to recalculate things all over.
A 600W PSU is still plenty. Hell, you could go down to about 500W at the minimum. Read the spoiler if you really want an explanation.
In my experience a relatively high-end system with multiple hard drives does not consume, from the wall, more than 250W using a Kill-A-Watt. The most taxing power-wise one of my systems pulled was about 350W. Overclocked graphics cards don't consume that much more power (I've had two in the power hungry system). Hard drives and fans sip power compared to the rest of the system under load.
I mean, if you're taxing the system to 100%, which as far as I know is impossible unless you're just running Prime95 and Furmark 24/7, you're not going touch over 300W.
7. Oh and as to the 1333 clockspeed, given the rates of memory speed now clockspeed is not goign to get noticed for the rather heafty price of 1600 clockspeed memory now.
As far as I know, 1333 RAM from a decent company doesn't cost much more than 1600, which is why I've been fine recommending 1600.
