I already have two 24 inch 60hz monitors, so I`m planning on putting that one in the middle of them.
Do you think this PC would be able to run games like crysis 3 or bf3 (bf4 too) on max settings at 120fps+, while recording with fraps?
I also plan to do lots of video rendering and rendering animations in cinema 4d with this pc.
If you`re wondering about the storage, one of the drives will be just for fraps and rendered videos, because they tend to take up a lot of space. The SSD will be for all of my steam games and stuff like photoshop.
That looks close to my build. One thing you may not need is the Rampage motherboard if you'll only ever be using two video cards. I have the pro version which can handle up to 3. At that level, it's just a matter of preference, though. You'll need that PSU if you plan to add more 780s at some point, for sure.
You may have issues trying to pair the 3rd monitor that is not like the other two in a surround setup. I would say you should pick up two more of the Asus 144Hz monitors. Across 3 screens, you won't be getting 120+, but you surely will on one. My framerates with everything pegged are over 120fps pretty regularly in BF3 with full-on AA and details. Also, from what I understand, newer versions of FRAPS doesn't drop framerates nearly as much as the older versions did. Plus, Nvidia will be introducing their own video recording software (ShadowPlay) within the next month or two that minimizes the impact on framerates and encodes straight to H.264.
I would get another 120 or 128GB SSD and put just the OS/System utilities on it. That way, if a new SATA standard comes out (eg SATA IV), you can quickly replace your OS drive with an equally small faster drive while boosting overall system performance after an architecture upgrade (though it may require a new Windows license).
Also, I'm not sold on Windows 8 yet. I don't think it's worth the quirkiness or the two separate interfaces. I'm curious to see what the 8.1 release has to offer, but still think it's more geared toward a touchscreen environment.
