Hello , a friend of mine used to have a R9 290X but it broke down so now he's using a HD 7970 . So my question is : Should he buy a R9 280X and Xfire or should he buy a R9 390 . He's got a Corsair CX 650 W PSU . He will be playing on 1080P. The Price difference between R9 280X and R9 390 is about 50 euros .

dont xfire on a corsair CX, really... dont.

 

quoting corsair's website: "an excellent choice for basic system builds"

Thanks for telling me that .

 

Sell the 7970 and he gets a 390 cheaper than a 280X

 

( ͡° ͜ʖ ͡°)

Hmm if he sells the 7970 and gets enough money , is the R9 390X worth it over the R9 390 ?

If he's only playing on 1080p not really unless he want 144hz

It's just really not a PSU to pair high end GPUs that output a lot of heat because the CX has poorer quality capacitors and only a 30C tolerance when the 390 can get upto 95C without overheating so...

Do yourself a favor and don't cf the 7970... it's a stutter fest. While the cards are individually awesome, the architecture of the 7970 and 7950 didn't handle cf as well as it should and caused way too much micro-stutter. I had 2x 7950 vapor x and at the the time it felt like a huge upgrade switching to an r9 290....

Then what PSU would you recommend in the price range of a CX? That's good enough to hold a R9 390 ?

Not really can you find any Seasonic or XFX models? Those are always good

I see you have a Coolermaster 600B , would that be good enough for a R9 390 ?

Why go with a worse PSU if you can get a good one? Go with the Seasonic S12II

It's an okay-ish PSU. But I would recommend the SeaSonic

EVGA B series, Seasonic 620, those are decent. IMHO, if you want more performance than a 390, a 980 or a fury make more sense. A 390X is not much better.

Was just asking , anyways that PSU is more expensive than the Seasonic S12II ...
