Here's my current setup for the past 9 months (ish). Some changes were made since my last post (a 2nd 2TB RAID array was added).
CPU: 2700K @ 4.5Ghz (Watercooled with the Corsair H80)
Motherboard: Gigabyte GA-Z68X-UD5-B3
Memory: 8GB Corsair XMS3 @ 1600Mhz
GPU: 2 x GeForce GTX 680
Displays: 3x BenQ XL2420T @ 120Hz
PSU: Corsair AX-1200
Sound: Creative Sound Blaster X-Fi PCI-E
Storage(1): SSD: Kingston Hyper-X 240GB.
Storage(2): Intel ICH10R: RAID0: 2x Western Digital Black Edition 2TB.
Storage(3): Intel ICH10R: RAID0: 2x Western Digital Black Edition 1TB.
Case: Thermaltake Overseer RX-I
Desk: IKEA Large Galant (Black Glass)
General Desktop and WoW (it's the only game I run in a Window, for convenience)
Under-Desk cabling - DVI-D, multiple USB extensions, Power Cables, Audio & various others
With the side cover removed
GeForce GTX 680 SLI
Some other notes:
- The system is heavily dust filtered. I have dust filters covering all fan intakes, with a dual layer super-fine filter covering the high CFM CPU heat exchanger fans. In addition to that, I perform a weekly vacuum on all dust filters and an internal clean using a DataVac Electric Duster.
- It's barely powerful enough for my requirements. 2x680 just doesn't cut it with the latest games such as Far Cry 3 in anything above Medium. Ideally I need 2 x 690, although I'm just waiting now for the 700 series.
- It's running a meticulously clean and efficient copy of Windows 8 (i.e. absolutely no unnecessary services or anything that might use the CPU above absolute minimums).
- I can't stand any game running < 60fps (it's just a painful experience on the eyes and a miserable experience in-game). Ideally I have games running at 120fps V-Sync, but that's just not feasible without additional GPUs (again, waiting for next generation hardware).
- All-in-all not as expensive as you might think. If you're a computer enthusiast, this really isn't anything special at all.
- Everything runs as a single desktop @ 5760x1080 (SLI/Surround). Some games I run Bezel-corrected @ 6080x1080.
That's about all.. Hope this was useful and might inspire some people to go multi-monitor gaming! It's an awesome experience and once you go you'll never look back. I practically cry when I see a game running on a single screen now
