None of the items have arrived yet and can be sent back if needed.
What I would like to know is:
1) Have I made any serious mistakes with my purchases? (main worries are the memory, and if the windows 7 system builder version was a good choice?)
2) Is the RAM i have chosen compatable with the motherboard?
3) will I be able to get a decent overclock with the CPU?
And finally as a bonus question
Any suggestions for two new graphics cards SLI (I personally prefer Nvidia, Any Price) or if another GTX 550ti will be good enough?
Judging from the components listed, this is an editing rig?
We need more info about what you want from the machine, because if it were a purely editing/rendering rig with some light gaming, youv got it right. But for a proper gaming build youv got your money tied in the wrong places.
anyway the questions.
1. Depends on what you want it do do. The RAM and Windows 7 OEM shouldnt be a problem.
2. Yes. Its an X79 platform and the RAM lists itself as compatible with it.
3. Do not know much about overclocking on X79, but if it follows Intels marketing scheme, no. No "K" on the CPU means limited overclock ability. Temp wise you fine with your probably overkill watercooler.
If you were going to SLI anything, get a bigger PSU, 750W for dual.
The whole X79 platform is a bit overkill, a Z77 would be fine and work out cheaper. You would also get more options as X79 isnt really consumer grade, its more for running large scale business servers.
A Z77 mobo, say an AsRock Z77 Extreme4, an i7-3770k, 16GB of 1600Mhz CL8 RAM, a GTX670 and a 600W PSU would form the basis of a good editing rig. Throw in a good cooler and stuff like HDD's and SSD's and youd have yourself a fine editing/gaming rig.
