What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.

I want to play games such as Diablo 3 on highest settings, while being able to watch videos or livestreams on my other monitor. Games I play include Starcraft, league of legends, smite, battlefield 3 and others. I can get more specific in the comment section

What is your maximum budget before rebates/shipping/taxes?

The maximum budget is about 600€, though I hope it to be around 550€, if possible

When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.

Within the next couple of days (specifically thursday, october 2nd).

What, exactly, do you need included in the budget? (Tower/OS/monitor/keyboard/mouse/etc)

I have a sound system, 2 monitors, a keyboard and a mouse as well as a windows 8 key.

Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?

As it says in the title, Germany.

If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.

I have 2 monitors from LG, Flatron W2443T, a keyboard and a mouse from DELL and a speaker system from Phillips, model spa5300/10

Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?

At the moment I am not planning on it, though I guess I might want to try somewhere down the line

Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)

I want about a TB of storage, SSD not necessary.

Do you have any specific case preferences (Size like ITX/microATX/mid-tower/full-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?

I would like a window and perhaps some colored LEDs inside, though it is absolutely optional and the case will be one of the first parts I would take budget away from, assuming it is good enough that overheating is not a concern

Do you need a copy of Windows 7 or 8.1 included in the budget? If you do need one included, do you have a preference for one or the other?

I have a copy of Windows 8.1.

Extra info or particulars:

The dual monitor functions are really important to me, other than that (of course)I want to to be able to surf reasonably quickly, write papers for university on it and maybe write a programm or another on eclipse. Some good amount of RAM would be very nice

Thank you everyone in advance! Makromag
