1: Having those drives, would it be possible, (and useful) to setup the hard drives to use the SSD for only the OS, the 120's in RAID0 for video programs (Sony Vegas/AAE) and the 2TB for all my games? (since the Mobo has 3 controllers)
2: Should I swap anything around for better maximizing? My pricerange total is ~2000USD.
This PC needs to last a while, but be usable for all my applications. Any other questions for me please let me know, I will answer as soon as possible. I would like to order this asap so I can get it up and running quickly. Thank you.
Actually, you should have all your games on the faster drives for faster load times, I just use the slower drives for files and stuff. (pictures, etc.)
You really went overkill on the CPU. If you really want an i7 get the 3770K or non K edition if not OCing. Otherwise, an i5 is your best bet. I recommend the i5 3570K or non K. For the motherboard, an Asrock Extreme4 or Extreme6 is my recommendation if you are getting the Ivy Bridge processors.
8Gbs of RAM is more than enough for most people. I suggest getting a pair of 4GBs then just add in more if you feel like you need more RAM. (keep in mind that if you multi task alot then that 16GBs will be totally fine.)
You might want another 6990 for the sheer performance it will give, but thats just me.
Seeing your signature, I see no reason to upgrade. All you will really need is an extra GPU.
My issue with my current system, which may be PSU/MOBO, is that Sony Vegas, Firefox and AAE all crash within minutes of use. Firefox crashes almost instantly. I am quite busy, and find it hard to troubleshoot on my offtime. Also, another GPU? That damn thing is so hard to find anywhere, lol.
Also, I am a big gamer, and I edit gaming clips. I am unable to record BF3 or anything else with Fraps. Framerate drops dramatically and makes it unable to destroy people AND record at the same time. I have another card that does recording, but not sure if it is worth it yet.
