Will this build work?

[davidabutler1981]

I am looking to build a gaming computer with a budget of around $1700-2000 and the capability to upgrade later.
I will mainly be playing FPS probably while blasting music and downloading from utorrent so multitasking is a must. I will also be using the pc for movies, music, downloading, streaming, and once classes start I will be using it for school (computer and network security) so with all this in mind this is what I have...

this is the list of parts I have come up with... the only thing not included in that list is the grafix card (I could not find it on pcpart picker)
the one I was thinking about is ASUS ROG MARS760-4GD5 G-SYNC Support GeForce GTX 760x2 4GB 512-Bit GDDR5 PCI Exp it is 499.99 on ebay.

A few other things... should I get a separate ssd for my os?
should I think about a better/ different mobo? I will have to run a wireless network card and that will take up one of my pci-exp slots... meaning if I run two grafix cards in sli or crossfire at a later date I wouldn't be able to get a good sound card because of lack of pci-exp slots. Any thoughts? ... oh and I love the red and black color scheme so with any suggestions please keep that in mind

also any input on virus, malware, spyware, etc protection is very much appreciated

Rather than getting an I5 with a $130 cooler, you'd be much better getting an I7 with a $30 cooler. It'll help a lot for multitasking.

Will this be my best option for gaming also and what version of the i7 would you suggest?

Except you're not only gaming. If you were just gaming, I would recommend the I5 any day, but you are streaming, downloading, listening to music, and more all at once. I recommend the I7-4790K

The video card you are looking at is a terrible buy.

Not that I am advising you purchase this card... http://www.ebay.com/itm/EVGA-Nvidia-GTX-690-4GB-RAM-04G-P4-2690-BR-Dual-GPU-04G-P4-2690-KR-/231520063167?pt=LH_DefaultDomain_0&hash=item35e7abcebf

But it is far faster and somehow cheaper as well.

I would simply look to a GTX 970 or something new from AMD when the new cards are released.
