AMD cards running better on AMD CPUs and boards is a load of crap, in fact, the opposite should be true. Both AMD and NVIDIA use Intel machines to bench their products, and most reviewers do too. AMD's fastest platform doesn't even support PCIe 3.0 on top of that, though thankfully you can get a chipset with two PCIe 2.0 x16 slots.
The problem I feel we have might be forced overclocks on improperly binned products, whether it be the GPU or its memory. GPU voltage supposedly varies depending on the ASIC rating too, which may be why flashing my 290 with a 1040MHz BIOS is unstable, because my ASIC rating is 85% and the chip runs fine at even 1100MHz core, though with a 75mV increase in Afterburner. RAM seems randomly good or bad too, and maybe even the memory controller may be at fault too. My 290 can do 1500MHz on the RAM which my 280X can't do, but my ancient reference 7970 beats both.
shit, the reason why I went with red this time was cuz the drivers from green had been crashing my 460 1gb for the last 1.5 years, every single driver release, not joking, was stuck using 1+ year old drivers. I just can't seem to catch a break. I swear I have the worst luck
just because of the mining craze, the quality went to shit cuz they want to meet demand.
@odemmah bro, just like I told you. get on hardwareswap on reddit. buy a used card from there. you can ask the seller questions and get quick answers. even if you want an asus one, you can still get a good one if you asked the sellers before you buy. that way, you can get a 100% problem free card. I made a huge mistake of buying this card from ebay, from a seller selling 20+ cards. there is no way he tested them all. he was lying when he told me it was problem free. it does have warranty but spending 50$ for shipping both ways, and a high chance of getting the same card back without a fix. it just isn't worth it when the card I bought only cost 175$ basically in my case, I would rather buy a new card than RMA. if you want a 280x no matter what, buy used from hwswap on reddit. just need to ask simple question, does it have artifact problems(most sellers list the problems of their cards - if it has any + have pictures), and you are set once you find the one with the right price. I wish I had known about it before I bought mine. shit luck. good luck with your purchase.
ps: one of the reasons I bought a used card was to avoid problems with new cards. I got lied to by an ebayer. got fucked over. no recourse as I gave positive feedback when I pop the card into my pc, everything worked fine. artifacts started poping up a few days later. game restart or pc restart fixes it. I fucking hate inconsistent problems, if it is, I could at least rma it. it is like aids of the gpu, never ever goes away.
