1, Faster than the Titan-X @ 1080P - 1440P - 4K

5 Faster than the GTX 980 @ 1080P - 1440P - 4K (Faster = over +5%)

But at 4K the performance gap to the 980 will increase and it will close in on the titanX.

Updated.

Slower than the Titan X on all fronts.

Faster than the 980 on all fronts.

By what percentage, 'To be continued'

1, Faster than the Titan-X @ 1080P - 1440P - 4K (Faster = over +5%)

4k it's gonna spank the **** out of the T-X

Everywhere else? Unknown....

as fast as 295 x2 on single card

lol, 290X, do you want me to put that under "9, 94% or less the performance of a 980."

Deleted.

3, With in +/- ~5% of a Titan-X @ 1080P - 1440P - 4K


I reckon it'll be 5% slower but 50% cheaper

Done. TwsT i also put you on the board.

No. 1

Done. i wonder if AMDMatt will take a guess at this?

4.

A lot of people could be wrong about the performance of the 390X due to lots of new variables.

Not if i want to keep my job.

i think performance will be slap bang in between the 980 and titan x

Ooooh interesting. That means he knows already.......

Have to say I've been Nvidia for years now, and have a Gsync monitor, but if the 390X comes up tip top toppety trumps, it's going to totally confuse my new gaming build I'm doing in a few months time.
