OK i just recently built a new gaming rig. I'm just curious if anyone has any recommendations on how to improve the system even more or what other upgrades would anyone recommend. Here is what i currently have.
Case: Corsair 800D
CPU: I7 970
MOBO: ASUS P6X58D-E LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX
RAM: CORSAIR DOMINATOR 12GB (3 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
GPU: 3x Radeon HD 5870 (Cypress XT) 1GB 256-bit DDR5
SSD: 2x Crucial RealSSD C300 CTFDDAC128MAG-1G1 2.5" 128GB SATA III in raid 0
PSU: ENERMAX REVOLUTION85+ ERV1050EWT 1050W
Drives: Pioneer CD/DVD Burner, LG Black 10X Blu-ray Burner
Any internal upgrades short of another 12gb of RAM would be a waste of money, as Jack said. That's the blunt truth until technology advances again in the future. There's no way that the i7-980x will give you anything close to another $1,000 of performance.
Maybe you'd want to try liquid-cooling or something like that... takes a lot of time and energy to do, though, and isn't nearly as maintenance-free as a good air-cooler.
I'd say go for peripherals. If you don't already, get an Eyefinity setup of three 1080p monitors.
If you do, get a soundcard and a pair of the best headphones you can find. More specifically, the Asus Xonar Essence (although I don't know if your PCIe x1 port is still available with the three 5870s), and a pair of AKG K701s. You'll want that card for those considering the power they need, and the fact that it has an integrated headphone amp. You'll have to check and see if that x1 slot is still usable, though... If you're a speaker guy, go get a Bose Acoustimass system and the Creative SoundBlaster X-Fi Titanium Fatal1ty Professional card. Either one of those would really make everything ,more entertaining if you don't already have a high-end sound system.
If you already have all that, go out and buy the most expensive office chair you can find, because your PC is the absolute best it can possibly be.
My comment on the RAID of C300s, performance will degrade over time as you won't be able to TRIM these drive; they have garbage collection, it's not as effective as TRIM, but it will prevent performance from reaching abysmal levels. I would rather use a single drive for OS and basic programs then add a 3-5 disk RAID5 array for storage and be protected from HW failure.
If you are to spend that much money on a rig, make sure you get a great monitor to go with it (or multiple monitors).
You might want to invest in a water cooling system, probably one of the part that will loose less of it's value over time with casing, PSU and monitor. You would also be able to reuse most if not all of it with your next PC.
Heh, we all have those days. Probably the same reason my CPU cooler is mounted backwards in my case right now... oh well...
I agree with Zenthar on that - I didn't see that there were RAIDed SSDs in that build. If I were you, I'd break that RAID array and use maybe one for the OS and another for Applications. I'd get probably 3-6 of the high-rated Western Digital Caviar Blue HDDs and put them in RAID-5. They seem to be more reliable than the Caviar Black drives, and I'd say they would be perfect for data storage. I would say you could get an add-in SATA RAID card, but your 5870s are taking up basically all of your expansion slots.
