There is no single best brand. Some manufacturers have their top-of-the-line card for each GPU, but the chip is essentially the same (might be factory overclocked). The amount of memory may also be different, in addition to the fan(s) and possibly the PCIe power connectors available (probably not for the 1080ti, but in general).
For example, with 24/7 mining, I would avoid buying single-fan 1060-based cards designed for compact mini-ITX cases unless a significant price difference made it worth it. 1060s with 2 fans or a blower-style cooler would be preferable.
Some people swear by certain brands, but it tends to be pretty hit-and-miss. No manufacturer guarantees you'll get the memory manufacturer you want (Samsung vs Micron, Hynix, etc.), or that your card won't be DOA. Customer service experiences and whatnot also vary case-by-case. Look closely at the warranty periods available, if the differences are of importance to you.
Thanks for replying.
You mentioned the memory manifacturer: why is this important? I thought it would be important only for the chance to flash the gpu, but not for any other reason.
Samsung memory generally gives you more flexibility when changing memory clock settings. All units are different regardless of memory brand, but it is quite common for cards with Samsung memory to have better overclocking potential.
Hello guys,
I'm trying to get into mining. My current setup(PC) is as follows:
Motherboard - ASUS B150M Pro Gaming
CPU - INTEL I5-6400 /2.7G/6MB/BOX/LGA1151
2x8G DDR4 2666 KINGSTON HPX FURY
GPU - GIGABYTE GeForce GTX 1050 Ti OC 4GB GDDR5
PSU - Fortron Power Supply FSP500-60APN 85+ 500W
SSD - Transcend 128GB MLC SATA III 6Gb/s
I'm looking into investing another ~300$ for a GPU.I have 2 PCIe x1 slots. Can someone give me a few suggestions on what to invest in and what currency to mine.
Thanks in advance to anyone that find the time to help.
I'm sure you know that GPU mining is never a sure investment, and there's no guarantee that you'll see ROI or that you'll see better results than if you just took your USD and exchanged it for some kind(s) of crypto in hopes of them having a greater value in the future.
With about $300, I'd consider going for a used RX 470/480/570/580 and mining Ethereum. You might also consider a new or used gtx 1060 (6gb or 3gb), which could be cheaper. There seems to be a significant price gap between the 1060s (around 200-300 for most models) and 1070s (mostly over $400). With a 1060, I'd recommend mining either Ethereum or Zcash. (The 3GB version may be more suitable for Zcash than ETH.)
To make the best use of the slots you have on that one board, 1080ti cards would probably be your best bet, but that's way over your budget. (And you'd probably want another PSU.)
, In ETH/ETC and good for XMR also.
