Is it good Gaming PC ?

You have no case lol

Definitely get yourself a SSD: a Crucial M4 128GB at minimum, though you're probably going to want to get two and put them in raid.

Get a better GPU: and go with dual SLI: the ones Vantanan mentioned are the way to go. That'll still let you run 4 monitors while being easier on the PSU. Besides, you only have 3 PCIe 3.0 slots. If you run a quad SLI setup, you'll be using a PCIe 2.0 port as well and drop the whole shebang down. Use two GPUs for the x16 slots imo (the 3rd 3.0 port is x8).

If you'll be doing anything with audio, you might consider a sound card too. If your work would be limited to graphical then onboard is fine though.

Finally, if you change later on to a Xeon CPU you'll need to buy a new motherboard too. They use a different socket.

yes it is a good gaming PC

um sounds abit excessive as 8gbs ram would do the games just fine.no games in the world use that much power.my friend has a lower spec gaming computer with like 3ghz processor 1tb hdd and 8gb ram and his gajmes run fine

That's a horrible choice for a gaming PC. Why?

1. Hexacore = waste of power and money, games don't really use up much cores, let alone six. Sticking with an Intel i5-2500K would be the wisest route. Of course, having mentioned this you'd also need to change up your board from LGA 2011 to a LGA 1155.

2. 32GB of RAM = Total waste, games only need 4GB. Having 8GB would be more than enough.

3. So, you go for a extreme series newest generation processor, 32GB of RAM, and still go for the already outclassed GTX 580? Well, besides quad-SLI being kind of pointless, there's already the GTX 680, or alternatively the Radeon HD 7970.

4. 1200W/1300W might not be enough to power that whole system with four power hoggers like the GTX 580, especially overclocked, so you should look more deeply into the power consumption and evaluate accordingly.

5. Storage - No SSD? Such a beast of a machine and without a vital component? Please place a lightning fast SSD into that build, it will at least make games load noticeable faster.

6. What about monitor setup? That would about try and justify aiming for a quad-SLI setup, because if only having one 1920 x 1080 monitor is the idea then most of the time three of the four video cards will be close to idle, having their power put to waste.

Bottom line, it's an overkill PC for gaming as it excels in everything, including high threaded applications and massive multitasking. Don't get me wrong, it will easily run games, but it's just the most expensive way to get to that. A simple machine with an i5-2500K, 8GB RAM, a good and fast SSD, two video cards (GTX 680's or HD 7970's), a top quality ~850W power supply and a good monitor setup would do the same for less than half the price. But still, if money is far away from being a problem and you simply want the best available then please, by all means, get that setup, but include the changes to the graphics cards, correctly evaluate power consumption for a accurate choosing of a power supply, add a good quality, fast SSD and get an epic monitor setup (3, 4, 5 or even 6).

EDIT: Since you've added that extra information, the components of the PC can actually make some sense now, as it's not only just for gaming. Yet, the above recommendations on the SSD, power supply, monitor setup and video cards still apply.

Cheers,

Vatanan.

of course its a good gaming pc,

but dont you think that 32gb ram is surplus for gaming?
