For Nvidia EVGA is my go to brand. Too bad they don't deal with AMD GPUs, but perhaps the cards are crap compared to Nvidia so they feel they couldn't stand behind them.
10 years in usa and canada, no other company can beat that.
I think sapphire is 12 months only. I like dual bios and sapphire is the only one that offers that.
I like the Dual Bios as well and wish more company's offered it, but one feature doesn't change the fact they manufacture sub-par products. I own quite a few cards from various manufacturers and it is Sapphire that I consistently have trouble with. I got two cards in for RMA right now and they are giving me static and trying to charge me to repair them.
The big problem is they hand their warranty off to Althon Micro which IMHO isn't very good. I suppose they bid for the work and they submitted a cheap bid, now that they are being flooded with defective products so they try to weasel out from the warranty terms. The first two times I had to send a card in to Althon it was no problem, they returned a new or refurbished card within a week or so. Then the 3 and 4th ones (this is over a period of about 18 months, not all at once) I had to answer a barrage of questions, did I remove the heatsink, no, and on and on. After feeling me out to see if I modified or abused the GPU they finally honored the warranty.
This got worse every time one of their crap cards would die until now where they are claiming based on my past RMA's I must be doing something to them. I try explaining I have lots of cards, Sapphire and many other brands and it is the Sapphires that keep dying and I treat them no differently. Then they mention mining and I state the box and advertising indicate they run OpenCL and yes I am using a OpenCL program 24/7. Then they give me static about these are meant for gaming, blah, blah basically trying to get out of repairing their defective cards.
Out of all my current AMD GPUs (RX570 through RX580's and a few Vegas) I would say Sapphire only represents about 20% while MSI probably is 50%, and XFX, Asus, and Gigabyte round out the remaining 30%. Out of all these cards during a 18 month period I have had to send 2 back to MSI, 1 to XFX and 1 to Gigabyte and over a dozen to Sapphire. So just looking at the ratio of failed cards versus the number of each owned I can safely say that Sapphire has a lower quality control than the others.
