But a 980ti will hit 1500MHz easy, while most 390x (And generally Hawaii cards) will do 1150MHz? 1200MHz tops. Each architecture has its strengths and weaknesses and we've known for a while.

What would be really interesting is a comparison of a max overclocked 290x/390x to a max overclocked 980 (non-ti). I think they may be going neck to neck...

It's not about clocks. It's about performance when you compare the offerings from each camp.

When you consider overclocking, the topic should shift to frequency/performance scaling.

Nvidia happens to reach higher clocks but that can be a misinformation. Remember GPU BOOST?

It may just be their term for throttling. When you heat up Maxwell, Boost will not hit it's target. So too, if you happen to reach the card's TDP Limit.

Instead of saying, the card is designed to clock at 1400 and throttle down when exceeds defined limits for example, they say, the card is clocked at 1250 and boost to 1400 if you keep it cool and not hitting it's limits.

Yup. For Maxwell to perform as well as they should, they need a custom bios and a custom fan curve. Water cooling is obviously better, but...that's true of anything. = P

thatswhy you disable boost, and use static clocks for loads.

Most do, with a custom bios...yeah

When I play CoD BO3 for hours on end my card hits max 70°C on the core and the same for the VRM's. Maybe I got lucky?

Those are good temps but take into consideration ambient temps effect internal temps, I'm in the desert so summer will take a toll on my card unless I run the AC all day but I have the same card as you do OC edition

my options are, msi, gigabyte, xfx, asus. the sapphire nitro is sold out.

Don't be like me, I skimped on the research to getting a 390 I ended up with the Asus card but I'm on the verge of exchanging it for an MSI or go back to Sapphire as I always had for the past almost 10 years

XFXs version is solid I hear plus lifetime warranty if registered through their site iirc

Power color is also a good option as well, but Sapphire has been with AMD for a very long time so they know how to make proper cards especially with good cooling

XFX, MSI, Sapphire and Power Color would be something I'd look into

BTW Out of the four I recommend I believe the Sapphire and Power Color are the longest cards so make sure to do some measuring and research to make sure it'll fit

Summer is the time for undervolting. I can run my 390 at -100 mV and 1035 mhz and it's a good 50-100w below the stock voltage overclock. You definitely don't want high wattage when the ac is running; that's electricity you have to pay for twice.

Many of us do not upgrade that often smile.gif
For me it seems to be every 5-6 years.

*That is also why those 8 Gigs are important.

I appreciate it, i'm going to go MSI. I'm RMAing an XFX right now, that was a lemon from day 1. Also they're out of sapphire's and they dont carry any power colors.

I have an Msi, no complaints yet other than some slight coil wine, which, i cannot hear over the noise from gaming anyways. But i know it's there so it bugs me. But great card thus far, 390. thumb.gif
Now just need to Oc it, not sure it's worth the hassle though for the minimal performance bump especially since im only 1080p gaming.

Ah I see, well I live where it can get hot in the summer but damn cold in the winter.
If I were you I'd RMA it and go with Sapphire. My previous one (HD 5970) was a Sapphire and i was really happy with it. But the ASUS was cheaper and I heard good things about it, so i went with that card.
