GPU's: 2x GTX 680 4GB (EVGA), SLI - At the time I bought these I was planning to run everything in 3 monitor surround, that's why I went with SLI and 4GB of VRAM instead of the standard 2GB at the time. I stopped using Surround about 6 months after building the computer- too many compatibility problems, not enough benefit. 4GB of VRAM rarely gets utilized with 1080 resolutions (the only game that manages to come close is Civilization V). SLI also (rarely) has some compatibility problems. This setup is capable of higher resolutions (I could do 4K) but with current monitor technology/prices it's not feasible. I really love these GPU's and I'm a fan of Nvidia's technology, but I could have saved myself some dough by using a single card or buying the 2GB versions.
Monitors: 1x ASUS VG278HE, 2x ASUS VS239H-P - I started out with 3x VS23's when I was using Surround. They were great for that purpose, but when I decided Surround wasn't working out I opted for high refresh rate (better for FPS gaming) on a single large monitor. I replaced my center 23" 60hz IPS with a 27" 144hz TN (kept the 2 side monitors). I definitely recommend high refresh monitors- makes Battlefield appear smoother- though you'll sacrifice some color depth/contrast. Having 3 monitors is great even without Surround.
Keyboard: Logitech G710+ - I upgraded a few months ago from my Microsoft Sidewinder X4 that was wearing out. Many people are religious about mechanical keyboards, I don't buy into it. The Logitechs are inexpensive but durable entry level mechanical boards with good features (I really wanted to keep the 10-key and Macro's, which most other mechanicals don't have). It's good for the most part- keys are more responsive (most of the time) and it's not terribly loud with the clackity-clack (though sometimes people on TS will hear me typing).
Quick mention- Logitech used to put screens on their gaming keyboards, but now that everyone has a smart phone and/or tablet, they've quit using onboard screens and started developing an app. Check out the
Logitech ARX Control if you're into that sort of thing. I don't think you even need to own a Logitech product to utilize the app.
Headset: Logitech H800 - Good headset for general use, not necessarily for gaming. I'll probably upgrade to a better set some time soon. Open to suggestion.
Mouse: Razer Imperator - Bought it crazy cheap years ago. Gets the job done. Should probably be replaced.
Mouse Pad: Glorious Extended Gaming Mouse Mat - Huge so I never run out of mouse space. Have had weights on the edges for months and it still doesn't lay completely flat without them. Idiots who sell it put their giant-assed logo in the lower-right corner so that your mouse drags on it; rotated 180 so stupid logo is under keyboard. Supposedly machine washable but who does that? Bought it on sale for cheap, no ragrets.
Guts/Other: 3770K not OC'd 'cause I'm lazy, ASRock Z77 Fatal1ty Pro, 16GB RAM because Adobe Premiere loves ram, some SSD's & HDD's to store all the bits.
And I'll end with this: If you don't have an SSD, do yourself the best computer-related favor you've ever done and get one. Running your operating system (and some games, like BF4) from an SSD is an amazing improvement over an HDD. An analogy I read recently was that upgrading to an SSD was like finally releasing a car's parking brake after driving around for years with the brakes on. Seriously- huge improvement, best money spent on improving your computing quality of life (though it will not necessarily improve gaming performance).
