upgrade to z87 now or wait for z170 later?

[PontiacGTX]

I am thinking about buying a another mobo but I dont know if the Asrock z87 OC Formula has a PLX to support 4 Way GPUs, or if i should spend 100% more thna the asrock price and see if I cna find a cheap quality z170 with 4 PCie, and buy ram(DDR4) and CPU(and a cheap placeholder)

I'm pretty sure it's not 2013-2014...

Not only is Z87 really outdated, but I recall 3 and 4 way GPU's getting nixed a while back.

Another ‘feature’ of the Z87 OC Formula is that the motherboard is equipped with four full length PCIe lanes, but no PLX8747 chip to increase the lane count. This means that the following GPU allocations are possible:

One GPU: x16 in PCIe 1
Two GPUs: x8/x8 in PCIe 1/3
Three GPUs: x8/x4/x4 in PCIe 1/2/3
Four GPUs: x8/x4/x4 + PCIe 2.0 x4 in PCIe 1/2/3/4

the asrock site shows it has a embedded PLX PEX8605, it isnt the same as the PEX8747

but still if the z87 price could be half the z170?

I honestly have no idea what you're talking about...or what the heck you're trying to do.

 

[PontiacGTX]

trying to use mgpu for more than 2GPUs.but I mean do you think is worth getting z170 evne that a z87 is half what a z170 mobo costs?

 

[EliteRetard]

I understand you want to use more than 2 GPUs, but why?

The only possible reason I can think to have more than 2 GPUs is for mining purposes...and I would think in that case the rest of the system doesn't matter as much (so Z87 might be fine). But I don't know enough about mining to really say one way or another, or if GPU mining is even a thing anymore (don't they have ASICs for that now?). And I'm not sure if you can use more than 2 GPUs in a system today, even for mining.

benchmarking...

 

[Valantar]

What GPUs do you have? If they're in a performance class worth benchmarking today (I.e. 1070 or above) why are you worrying about motherboard and CPU costs when you have that kind of money to toss around? And if they're not, why are you wasting your money buying multiple weak GPUs rather than pooling it for one that would perform better in 95% of games and benchmarks?

Maybe he is waiting for Vega 4x CF...Though honestly, a more modern platform would help a lot more for that. I would not consider Z170 either, I would go for SKL-X when out, or X99 now if you cannot wait. Again, for more than 2 GPUs, best to have an HEDT platform IMO.

Again, can anybody use more than 2 GPUs? I'm pretty sure Nvidia stopped supporting more than 2, does AMD still allow 3-4?

Yeah, AMD supports up to 4. The gains are minimal in any practical use vase, though. A true waste of money. Although I guess it would be fun to see the 3DMark scores of 4x RX 460, just for fun. Nvidia still supports 3- and 4-way SLI for benchmarking, but not for games.
