Hello I need some help picking CPU's I plan on gaming at 2560 × 1440 on a 27" monitor with max settings (highest settings) And i currently have a i7-4770k and Asus Maximus 6 Hero MOBO combo i am wondering if its worth getting the i7-4930k and Rampage IV Black Edition instead for 2 way SLI?

Can the i7-4770k and Asus Maximus 6 Hero Run 2 GPU's in SLI no problem with "ANY" GPU at x8x8 or should i go 2011 and get x16x16 on my 2 way SLI with i7-4930k and Rampage IV Black edition?

Will i see a big difference with x16x16 on 2011 with i7-4930k or Should i stay with i7-4770k and Asus Maximus 6 Hero at x8x8 in 2 way sli?

I am confused on how much of a difference will i see going with 2011 x16x16 being noob with PC's don't really understand if you could help me better understand this would be a great help!

Yes i know i7-4930k is probably overkill and that i7-4770k is as high end is it gets for gaming but if i want to do 2 way sli is it worth going 2011 for extra bandwidth x16x16?

Would probbaly run 2 way sli with 780 ti or dual titans

Well..... I think the 4770k and x8x8 sli would be plenty good enough, and if you already have the 4770k and Asus Maximus 6 Hero MOBO, it probably wouldn't be worth the extra money and effort to upgrade. Plus, the 4770k will have superior single core performance to the 4930k.

However, there's no denying the fact that the LGA2011/4930k would be better overall. It's far more future proof as well as it allows to get a 3rd 780ti or Titan later on down the road if you wanted. It also has more cache and memory bandwidth to go along with the 40 pci-e 3.0 lanes.

Hi ya i am having trouble understanding this is there a big difference between x16x16 vs x8x8 with say a 780ti in 2 way sli? would i be able to tell? and how much more extra fps would it be?

The most id ever do is 2 way sli btw

I do not know if there is a big difference between x16 vs x8, I believe GPUs that exist today are ok with x8, but at some point this will no longer be true (i.e. there is a future proofing consideration here). LGA 2011 pulls ahead with 3 way or 4 way SLI. With 3 or 4 GPUs, you could still be running at x8 because 40 PCIe lanes are available. With LGA 1150, you are limited to 16 PCIe lanes, so 3 way or 4 way SLI would force the cards into x4.

In other words, for 2 way SLI, you likely won't see a difference today, but in the future when x16 does start to make a real difference compared to x8, you will see a difference even in 2 way SLI. See this.

Thank you very useful information :)  what i think i will probably just do is go with 2011 and get a i7-4930k for future proofing Thanks guys for you're help!
