Hey, sorry for slow response guys.
Having multiple video cards installed generating very high frame rates may not benefit game play. Some consideration must be given to the refresh rate of the display.
Yes, i did research (very lightly) the screen. From what i read, getting 100fps on a 60Hz monitor is pointless. Luckily i went for a screen that's 120Hz. It's this one.
The multiple gfx is something that you guys don't have to take into consideration, as it is only an option later on. The only effect it will have on my build is the choice of MoBo and PSU. So for now, let's go with a single 680.
We will of course help you to build any thing you want but I am a little concerned that the build will become unbalanced and you will be spending money in expectoration of future super performance that may not be possible. So please do not be offended by me asking you to do some more reading, This one first, and you might look for similar.
I will of course read every article you guys send me to improve my understanding of hardware and PC builds. As i mentioned earlier, multiple 680s is an option in the future if needed. When it comes to the budget, I am willing to stretch it further if you think it will be worth it. I'm also purchasing the GPU and CPU over in the states, leaving more in the wallet for other parts (roughly 375$).
I should also note that this computer will also be used for 3d modelling in the future (going to study engineering), and from what i understand this software (mostly autocad) is very straining on the processor (hence the 3930k choice).
