so im buildig a new rig and im having trouble deciding between the 3930k and an x79 board or 2x e5-1660 and sr-x. I currently do about 50% video editing/encoding and 50% gaming. There are a few things i want out of this first to be as future proof as possible for at least like 4-5 years, then id like to be able to play any games for the next few years at max, and id like to encode lightning fast, also have the possibility of some 3d rendering. One more question to add will the x79's higher ram speeds be better than the mass quantity from the sr-x?

thanks for your help

Well, the SR-X is going to blow a single 3930k out of the water for editing / encoding. And gaming performance should be pretty close to equal, with the dual E5's pulling slightly ahead.

The SR-X is also quadchannel per CPU, so you shouldn't have any difference between the X79 and the SR-x for RAM, and they both support the same RAM speeds (I would go with 1600MHz, since OCing the RAM doesn't give you any real performance benefit.)

The only downside to the SR-x is the massive PSU needed to run it especially with SLI.

Also, if the price on the SR-X is a bit high to start with, you can always get a single CPU and add the second later.

thanks for our input, but are you sure about the ram? For instance the evga x79 ftw has 2133mhz support without oc and the sr-x tops out at 1600mhz so there really wont be a noticeable difference down the line?

anything over 1600MHz is overclocked, which is the default speed for the memory controller built into the CPU.

Xeon's are not Overclockable, which is why the SR-X tops out at 1600MHz, the i7 will require OCing to get to 2133MHz.

the difference between 1600MHz and 2133MHz is only a very small percentage in synthetic benchmarks (less than 5%) and in real world applications is not noticeable.

The biggest bottleneck you are going to run into is storage.

as in hdd storage? how would you recommend solving that? my current plan is using a ssd for my main probably a 240-256gb then using 2tb 7200 rpm hdd for my mass storage. Is there a better way than that? i know ocz has a 1tb ssd but considering the price of the buld i can't aford to spend $2,700 on one

A 256GB SSD would definitely help, but you are going to have to copy projects back and forth, because writing to the HDD is going to bottleneck you.

Using a couple of HDD's in RAID 0 will also give you a performance boost, but have something to back that data up to OFTEN since a failure of either drive will destroy all data.
