Well, the 980ti isn't a cool card by any means, but it's not 290x hot either. That's partially due to its sheer size. It's easier to transfer the same amount of heat from a 600sq.mm die than a 430-ish sq.mm one. Simple as that. But you do need a large cooler as the power consumption is pretty much the same, especially when overclocked. smile.gif

What temps were you getting at 50% fan speed on 390 Nitro?

Was getting about 71-74°C with winter temps and no heater in the house so it stays cool. Now with water im at 47°C with an ambient of about 28°C and no ac haha.

Core temps don't mean anything, VRM is what matters. And 47C is high for core temp under water.

Why would a custom loop require too much care and maintenance? I flush mine like once a year max without any issues.

The difference in shaders is 10% in favor of the 390x over the 390, so performance should be about 10% better, usually a bit less than that. Sometimes a bit more, depends on the title. But as far as I'm concerned, the power draw and thermals are identical as long as the cards are clocked equally and use the same voltage. And even if there is a difference, it'll be negligible, especially in thermals.

@buddatech

The performance difference depends on how each card overclocks. Ask him to tell you how his card overclocks at a certain voltage (Ask for VDDC, not the offset in Afterburner). If your card can overclock to, say, 1125MHz and his can overclock to 1175MHz, then I'd say go for it. If they are about the same or your card overclocks better, meh, not worth it from a performance standpoint.


Said that he never overclocked either of his 390x GPU'S

Hmmm... Well, XFX does have a good track record, but that means next to nothing. It's luck of the draw. What I'd do is overclock your card and, if it's a dud or mediocre start thinking about biting the bullet. But don't expect to be blown away by the difference by any means. smile.gif

no dont do it.


390x is like 5% faster. just overclock the 390
post #9860 of 11962
Thanks for all the answers pertaining to my question +Rep to all that provided advise/help. Think I will keep the 390 for now. As for overclocking the card I just started messing with it and was able to achieve 1125/1550 to start stable in only the couple games I've tried so far not done yet. All setting on auto max temp I saw was 62c max fan was 68% which was very audible will be making a custom profile for this guy.
