Getting a DDR4 compatible CPU. Help?

[Heisenburger]

I'm planning on moving to ddr4 ram, and was hoping to get the intel 5820k, but read that it only had 28 pci lanes, and this could affect the performance of 2 gpus in sli. Would the performance hit be so noticeable that I should save up for the 5930k? or will I be fine?

I have 2 gpus in SLI on mine... no issues. You'll be just fine.

You won't notice a performance difference running gpus in 16x and 8x.

There is hardly any drop between x8 and x16. So the answer is, unless you plan on running 4 cards the 5930k won't offer anything over the 5820k.

You should really be asking for help on DDR4 because you're switching CPU, not the other way round. DDR4 is not worth switching platform. 

 

28 lanes is more than fine for 2 way SLI. 4 way SLI is where you may need to go for the 5930K

seeing the 4790k *only* has 16 lanes, i'm pretty sure you're more than fine.

Thanks! I was just a bit worried since a few of the user reviews on new egg kept on mentioning the fact that it only had 28 lanes.

Well my current pc is pretty shitty, and I built it on a $350 budget, so I'm planning to go all out on this one, and I don't want to spend on a top end ddr3 mobo and cpu, if I'll have to do switch eventually.

You won't have to switch to X99... unless you're a content creator, there is zero reason to go X99.

What are you using the system for? X99 is a waste of money unless you're a content creator.

Apart from gaming I'm also going to be using Autocad and a whole lot.

Edit: plus 3DS max.
