questions about the i7 5820k

[SAV1OUR]

so i'm super tempted to skip getting my planed upgrades and getting x99 however within my budget limits i can't get my dream 5960x sadly so my only other option would be the 5820k. what i'm wondering is there any cons to the price because it seems so cheap for x99 

[OnCue]

Alot less PCI-E lanes than the higher end skus.

Wait for skylake, is it? Because you wont have to get a new motherboard afaik. It wont support DDR4 since it will use 1150 and z97 or z87 i think

what do you mean it will still be able to use the full boards pci slots

but more cores and ddr4

5820k - 28 pcie lanes max

5930k - 40 pcie lanes max

5960x - 40 pcie lanes max

 

Edit: I doubt that'll really make a difference when it comes to performance, as the i7 4790k only has 16 max

From what iv'e heard the 5820k only has enough lanes for 3 way SLI where the other processors can have upto 4 way SLI

Look at the performance difference between a 4930K and a 5820K, then look at the price difference, I'm sure you will be pleasantly surprised. I 'm not saying the 5820K is a bad chip though.

also with enthusiasts buying x99 I can only imagine the excess of used 3960x/3970X and 4960X chips around on the market.... if you wanted a extreme chip have you considered a used one.

just an option to think of mate.

the only reason i want to go to drr4 i know that sounds dumb but its the main attraction to x99 in my opinion

Lol why though. It makes no sense right now. It isnt worth the cost. Not even close.

for once i have enough money that doesn't need to be spent on anything else so it would be nice to get right on the new stuff but i don't know i'm still split

ok, then I guess it is the 5820K then

I am not sure if you can do 2 way SLI with that CPU. Maybe it would go 16x and 8x or not work at all. I heard some information that the 5820k is not that good for multiply cards. Look more into 5930k instead.

 

 

(correct me if I am wrong, don't yell:)

It will run up to 3 cards in 8x,8x,8x.

 

Z79 will run 2 cards with only 16 lanes the 5820K has 28 lanes so it will run 2 cards just fine.

2020 called they want their 9650 back  

 

 

anyways thanks

Haha oops thanks for that never noticed.

It's true that the 5820K only has 28 pcie lanes.

 

However, if the motherboard has PLX lane multipliers it doesn't matter how many lanes the CPU supports: the PLX chip will take the 28 pcie lanes and multiply them and you can get any combination of crossfire

 

Case in point, the Asus x99-E WS can support up to quad x16/x16/x16/x16 or even seven x16/x8/x8/x8/x16/x8/x8!

 

Of course there are some disadvantages to using the PLX chip; Mainly you get some latency between GPUs but it doesn't affect gaming all that much.

First Question: How Many Graphics Cards will you run?

[Legitsu]

DDR4 Isn't gonna give you any mystical performance gains nor will the 5820k stick with what you had 

[SAV1OUR]

First Question: How Many Graphics Cards will you run?

just one but ill be upgrading whenever the 1000 series or amd equivalent come out 

[airdeano]

with one GPU and future GPU upgrade figured, stay on your Z87.

i wouldn't jump on the bandwagon as of yet. yeah, you have the cash now, but

many things will change in the coming months/quarter. busting the budget now

will only delay future updates and at that time, the "sticker shock" will have

normalized and possibly make it more affordable. holidays approaching will

have many chances of special buys, but for now, i'd wait.

 

from some testing, the "update" gain is 20% over Has/DC (stock for stock) in

benchmarking. if you have a need for content creation, then it'd be a harder

choice, if hobbying with content creation, wait.

 

this platform will be around for another 4-5 years and improve in 2-3 years.
