    Hey there,

    I am about to upgrade my graphicscard to a Sapphire 390(X) Nitro. The X costs only 60 € more and so it's a hard decision. I wouldn't have payed the usual +100 € they charge, but this deal is kinda tempting.
    Sooo, what would you recommend? I am currently playing in 1080p but I will most likely upgrade to a higher resolution and freesync next year.

    with or without an overclock?

    i have not checked but going on my 280, with an oc of 1180/1430 i beat a stock 280X

    so i would say save the money and buy the 390 and the overclock it :)

    Its not like it will gonna be a more than 10-15% difference at best. Both 390/390X will do great at 1080p. That extra 60€ spend on 8GB system ram more or get an SSD.

    Get the 390 and OC it. The 390 non X is the magic spot imho.

    Most 390 have a lot of room for overclocking, easily giving them a 10% bonus in performance.
    I don't know how well the 390x overclocks, someone with more experience with them can tell you.

    If you're unsure whether or not it's worth the money, I would say don't do it.

    If you consider the 60 a small amount of money, go for the uncut silicon (the 390x).

    If it was me and this was a closed budget i will go for the extra 8 GB RAM and the 390 non X.

    Only 8 GB of system RAM for a 8 GB VRAM GPU is not a good combination.

    Too much usage of virtual RAM (pagefile.sys).

    Yeah spend a $150 for more DDR3 which will be useless soon, when 8GB is more then enough. Makes Sense!!!!

    $150 for an additional 8 GB DDR3 memory stick (or 2x4)?

    You should look better for deals bro! :nerd:

    You can buy 8 GB DDR3 for less than 30 US$.

    :rolleyes:

    yes go for r9 390 for sure at 10000 %

    r9 290 947mhz
    r9290 1000mhz =r9 290x 1000 mhz
    r9 390 1000 mhz = r9 290x at 1000 mhz
    r9 390 1050 mhz = r9 390x at 1050 mhz


    i have r9 290 oc to 1050 mhz hot spot i get avg of 7 10 fps +
    without touching the memory

    You forgot to add 3 "x" on the left side...

    i mean r9 390x at 1050 mhz = r9 390 at 1050 mhz and vis versa
    so r9 390 at same clock 1050 mhz = r9 390x at 1050mhz are same fps -60$ ^^

    That's not correct, 290/390 is a limited hardware version of the full "X" version.

    The base timings difference between X and non-X versions are not so important because you can set the same for both as you know.

    What you can´t change (PCS+ bios locked lucky ones...) is the 2 two main hardware differences between them:

    290X/390X GPUs has 2816 Unified Shaders, 176 Texture Mapping Units

    but 290/390 only has 2560 Unified Shaders, 160 Texture Mapping Units

    https://en.wikipedia.org/wiki/AMD_Radeon_Rx_200_series#Chipset_table

    https://en.wikipedia.org/wiki/AMD_Radeon_Rx_200_series#Chipset_table

    In any game or graphic benchmark performed in the same PC and with same software (OS, drivers, ect) setting equal timings for 290/390 GPU and 290x/390x will not equal performance between them.

    It will only shrink the FPS advantage of 290X/390X over 290/390.

    290x/390x will always outperform 290/390 in any fps test because it has more raw GPU power (hardware) available.

    Is like comparing the performance (top speed) of the same car engine with 12 cylinders enabled or 8 cylinders enabled.
