Can my i7 2600 run GTX 1080 + GTX 1080Ti(for mining, doesn't need SLI)

[HK1]

Hi, according to my calculations, i should be able to make $13 a day mining zCash.

I have a 1080ti and 1080, mining doesn't need SLI, should I buy the 1080ti? I'm just worried that if i put a 1080ti my i7 2600 will be a bottle neck with a 1080.

will my i7 2600 with 16 PCIe lanes be able to run these two cards?

I highly doubt it. I mean mining isn't as demanding on the gpu as brand new games but still. Ur CPU is too weak for a single gtx 1080ti, let alone a 1080 also.

If you want to minewith the 1080 only assign 1x or 4x pcie lanes to it, that way the 1080 ti should get full 8x bandwidth.

Why? considering Titan V is the first GPU to ever saturae PCIe 3.0 x16 I would't expect much throttling out of x8 gen 2.  A 1080 ti barely saturates x4 gen 3

i guess i have to go for it now lol

To be perfectly honest I myself would get a CPU upgrade + rx 580.  Once you optimize for monero you'll get great mining moolah off of the 580 and you can enjoy a very similar gaming experience.  Get two 580's and it will whup a single 1080 ti for mining

 

second hand X99 CPU + mobo - $300

RX 580 8gb - $250

$550, $800 if you get 2 580's

 

 

GTX 1080 ti - $700 - 800

I'm voting that your processor needs an upgrade, solely based on the way you worded it making me laugh a lot.

It should work. Mining motherboards rely on a myriad of x1 PCIe risers, so it's not like bandwidth seems that important for mining. I guess it depends on how the algorithm for your particular coin works, but the typical GPU mining rigs involve weak CPUs (like Pentium weak) and much more than 2 GPUs, even if they're 1080s, so...

all the work for mining is done on the GPU and very little data is passed to the CPU (which takes the form of a few bytes to send to the pool). The only thing it would be running is the mining application. I use a Celeron on the 3x1070 rig and the most load it sees is from RDP when i remote in. it otherwise sits mostly idle.

pff i tested my rx 580 on a first gen x16 pci-e board and gen 3 pci-e x1 board and both works perfectly (30 mh/s) even with a monitor connected to it. (the gen 1 board was with a xeon e5450. a frickin 10 year old CPU, u should be good for days)
