Overkill CPU and mobo. Replace them with an i5 3570K and Asrock Z77 Extreme4.
Get another 660Ti with the money from downgrading. Or you can just buy a 670 and add in another when needed/wanted.
Get a Vertex4 instead of the Vertex3.
After all that, build should perform like a beast, all while costing lower.
But just some quick feedback.
If general use and gaming is what the PC is going to be used for, the i7 is pointless.
only need 8GB of RAM for gaming, 16GB will be wasted.
Decent enough card.
Very expensive mobo, can get cheaper that will do the same.
Old SSD, get the Vertex 4.
Would this be enough for my video/photo editing and processing, because i am a photographer and i'm used to having editing programs running all the time. However my old computer was really slow and would freeze a lot which really annoyed me, that's why i require a powerful system (sorry i am new to all these computer technology and got someone to put my parts together).
The budget is not really an issue as i will spend money on a new system as long it does what i require it to do without freezing or slowing down.
That should do quite nicely. Just throw in Windows and a good case (The HAF-XM you picked earlier is a great choice), you will have yourself a fine editing and gaming rig, with the capability of overclocking and dual Crossfire/SLI.
