To me it's over priced but it is the top performing single gpu. I have to fight with myself on it, and i really dig the 980ti as well. I feel like the 980ti is legendary on overclocking and moving to smaller nodes we may see a lack of overclocking now. I almost got one of those zotac 980ti's... I have been tempted to build a green box and a red box. If i see super good deals i may nab one. I also want to toy with the rx 480 just because i like new tech. I feel like the 1080 will be like the 680gtx and i spent 500$ a pop on those @ launch and better stuff was there not long after.

Each to their own i suppose, i just don't see the point in popping all over the forums and being negative about a gpu. If it sucks i just mostly ignore it and move on or i might throw a joke or two out there.

AMD recognizes the problem and promises a driver fix by Tuesday 5th of July. Remains to be seen how the fix will effectively be implemented and if performance will be impacted due to lowered power limit.

AMD can lower the power limit via driver, this can stop the card from going over 150w, at the cost of performance. However, it remains to be seen if the distribution of power draw between motherboard 12V rails and the 6-pin connector will be affected. I believe it cannot be,not via driver fix.

Reducing overall power draw would be the goal. I don't think they can do anything about the distribution aspect through software. So clocks would have to be lowered and overall performance would have to be lowered.

One thing is for sure that aftermarket card can easily fix this problem.

Afther waching the stream of builzoid the conclution that came with him making some test was that the pcb of the rx480 is a mess. 3 VRM and the chip are powered by the 6 pin and the other 3 VRM and the vram are powered by the pic-e. Both the pcie and 6 pin work without tranfers power between each other so AMD can not offset power from the pci-e to the 6pin.

Also the 6pin its working with 3 ground pins when 1 of those should be used to reconize the conector as a 6pins wich doesn´t do.

Well that was what he found so is best to wait for AIB cards and also AIB cards with custom pcb since if they use the same pcb of the reference it will not matter if they put a 8pin or 5 8pin conectors since the pci-e will still use the same watts as is using now.

Lowering the vram my help reduce the watt usage of the card so maybe someone can test that.

sry for my english.

AIBs simply won't have this problem since i am thoroughly convinced its a firmware issue. using drivers instead of updating firmware isn't as desirable but easier to do globally.

it IS suppose to have 3 grounds; i am getting tired of posting the same specs over and over again but here:
Warning: Spoiler! (Click to show)

all that ground does it let the card know that it has a connector connected.

Honestly, I would think you would burn one of the two 24-pin connector 12v lines before the slot, as all motherboard +12v (except CPU) comes from that connector.

Also specifications like the 75W one are always very conservative, on a decent quality motherboard with a decent quality PSU I don't think you will run into too many issues. You can pull over 300W through the 8-pin CPU power plug, it gets warm as does the wiring, but you can still do it.

Based on my personal experience, my 12v pins in the 24pin main harness melted before the slots were damaged. This was with x3 7970s plugged into three un powered x1-x16 risers. My motherboard did not shut itself down to protect itself. This was in an open air (milk crate) mining rig when I first started. An extreme case I would think/hope.

From the PCPer video, they went into detail explaining that the pcie pins were rated for 1.1x5=5.5a total, unlike the gpu 6/+ pin connectirs that have much more to offer. Im eagerly awaiting to see AIB products.

I'm still stuck on how they got 11.4v droop on the 12v rail on a Corsair 1500w. That is insane, had to be a defective unit. Ive pushed OCZ, Corsair, and even Coolermaster PSU's HARD and never got anywhere near that amount of 12v rail droop. I'd send a PSU straight to the trash if it drooped that bad on any rail at anywhere near its rated load.

Then there is the spamming of this video.
Warning: Spoiler! (Click to show)
So i would conclude you are coming across as a Nvidia fanboy, but that's not accurate. You are someone who has bought some of the most expensive GPU currently and has previously bought cards like Asus Ares. I think your issue is your and enthusiast who looks down on lower end cards. with the exception of promoting the GTX 970 which leans you toward Nvidia fanboy zone.

I have to ask though why you care so much about hating on the RX 480 when you have a 1080gtx? It's obvious you were never going to buy it.

Edited for grammar crackers yum yum.

Im just being very real. All i said is facts. Sad facts. I was hoping for something better. We deserve better from amd. Im disappointed.
They dont learn from their mistakes.
Gtx 970 is still a good card and if you like nvidia then you dont do a mistake if you buy it over rx480, considering the same price.i wouldnt buy a reference 480 cuz of obvious reasons.
If theres afternarket rx480 then maybe the card will be ok.
At the moment with the reference card i cant say they keep what they promised and sadly they are 2 years behind nvidia in terms of architecture. The hype is just not there.
My belief in amd has cost me a lot of money. Freesync monitor, swapping different amd cards cuz always some issues with them then selling all of it...
My point with gtx 970 is ....choose wisely now with which team you want to go before its too late(buying monitors) cuz it will cost you a lot of money then to switch and 970 is not a bad choice if they cost the same.
