I am trying to build something that I can do a lot of photo/video (amateur) on as well as gaming. Also, thinking of not buying anything else in a some years to come. What are your thoughts? Some things like RAID card was hard to figure out if it was a good choice. Thanks a lot!
If you aren't gaming on three of those monitors, having two of those video cards is just... silly. I run most games on ultra at 120fps with a single GTX 670, and that card is more impressive than mine.
If you ARE running three monitors, get the 6GB VRAM version.
You could easily get away with a lesser power supply - 750w would do.
Personal preference, but I don't care for that mouse - it's shape and the way I hold mice made my hand hurt.
Since you have the money, why are you buying a cheapo keyboard? Do yourself a favor and get a mechanical keyboard. They're MILES better. (When I switched, I picked up 20 words a minute within the first five minutes.)
