Any difference between 4GB and 8GB cards? Almost impossible to find 8GB cards, but some 4GB are still around.
I got 6 Saphire Nitro + LE, but I paid A LOT for them.
Truly amazing where prices have gone in the past 30 days! I purchased two 580-based video cards right after Christmas - one Sapphire Nitro+ 580 4GB and one Asus ROG Strix 580 8GB "Top" OC edition. I bought an Asus ROG Strix GTX1080 8GB OC edition about two weeks before that for $560, also.
I paid nearly $350 for the Asus card, and just under $300 for the Sapphire. Looking around last night for "more of the same", the cheapest I could find the Asus "T8G" model is over $550 and the Sapphire Nitro+ 4GB is going for over $450 on eBay and unavailable for the most part on Amazon and NewEgg. That Asus 1080 has just evaporated, I guess - last price I can find was over $1000.
Those are STUPID expensive prices for cards, and I suppose that we miners are to blame for these absurd prices, because you just can't buy GPU cards for a reasonable price no matter where you look right now. Maybe there are a couple of places I don't normally look for them, but those have always been my 3 "goto" websites for computer parts of all types.
I was thinking about trying a GTX1070ti but those are priced around $800-$1000 right now. That's freakin' crazy! Since I am basically only doing Ethereum - at least for now with most other coins being strangled by ASIC devices, I guess that the 4GB cards are fine - for now. I read that the 4GB cards will likely be unusable for Ethereum beyond a certain epoch in the not too distant future (let's say a year?) when the DAG overruns that 4GB size, but the exact time that happens remains to be seen - at least for now.
