What Deemo said. An i5-3570k with a Hyper 212+, 8GB of RAM, a 2GB GTX 670/680, a Gigabyte z77x-ud3h, a 1 TB drive, and an SSD that ISN'T of a horribly unreliable brand would be a fraction of the price an only about 5-10% worse for gaming... which doesn't even matter because it would still completely max out any game on one monitor.
Do not got to ibuypower look at the reviews anywhere they are so so terrible. Sometimes something simple like HDD not plugged in but for 4000 you should not have to worry about something like that also customer service is terrible go somewhere else. I strongly suggest Maingear best PCs and honestly best customer service I ever seen compared to other big companies like digital storm plus no sales tax out of NJ otherwise stealth machines are good northwestern
Here's my build for you : http://pcpartpicker.com/p/qKby
for $2200 you get double 680s and a 3770, with a 240gb mushkin ssd and 1.5tb wd black, and a platinum rosewill psu 750W, and not to forget windows 7 pro. Even with 3 monitors, bigger psu and bigger ssd you'll still be under 3 grand.
At first I read that as a 4-way gtx 680 SLI and thought, "that's not a bad price at all", then reread it correctly. You're paying more than 100% markup on a $2000 rig from a company with a reputation for shoddy quality.
Assuming this is for gaming, you are stupidly overspending. That 'extreme' processor will never be a good cost-benefit choice; you are spending 60% more for *maybe* an extra 5% performance over the mainstream i7. They aren't meant to be gaming processors, and it's just gimmicky to think otherwise. 16GB of DDR3-1600? They couldn't even choose a better speed for $4k? That's like $60 worth of RAM, and I'm sure they picked out some high latency stuff too just to spite you.
The point is, you can build this PC from parts twice-over if you did it yourself. Unless you're actually making a thousand dollars an hour, it is more cost-effective to just build your own at this price; if you're worried about breaking something, spend $200 for a full, cheap build to practice on before dropping the maybe $2k this one costs- still more cost-effective and you'll gain the knowledge of your machine while doing so.
I'd go with angaddev's build for that price as well; I'd maybe swap out the PSU he suggested with a modular Seasonic for cheaper after promo code:
and would maybe consider putting in a bluray burner since that will only be a few drops more in the bucket, but otherwise, that's an impressive build, and will game scores better than the ibuypower.
This isn't a four thousand dollar computer, contrary to what the price tag tells you. Maybe you'll impress some of your less-knowledgeable friends by telling them you spent four grand on an ibuypower, but anyone who has interest in computers will laugh silently and try to convince you that snake oil will help overclock those gigaramz.
