Hi all,

I've as good as finished my intended build but it came to my attention recently that the Nvidia GTX 780 Ti that i had in my build (still there), might as well be exchanged for a Radeon R9 290x. I'm aware that it is a worse processor but i was wondering just how much worse it is and if it's a "bad" processor. Also, this "downgrade" will save me approx 300 dollars (just to give an idea of if it's worth it or not)
This is my build as it is right now

As one might think from my OP power supply i do intend to use crossfire eventually.

Thanks in advance!

EDIT: Just to avoid confusion (maybe it's just me) the r9 290x i'm talking about is this one http://pcpartpicker.com/part/sapphire-video-card-100361...

By changing to the R9-290X you would be going down one performance tier (for gaming) as shown in the chart found here http://www.tomshardware.com/reviews/gaming-graphics-car...
Check out this page of the article also http://www.tomshardware.com/reviews/gaming-graphics-car... where the GTX 780Ti and R9-290X are specifically addressed

Awesome, thank you, i was worried that this was gonna be a major step down but by the sounds of it it's not that huge. Nice info and thanks for the quick response.

I'm not sure how you think you'll be saving $300 going from 780 Ti to a 290x, but anyway.

The 290x and 780 Ti are very similar in performance, trading blows for top-spot depending on the game. Now that the 290x is coming back to normal pricing, the 290x is a better deal than the 780 Ti is, generally speaking, and is not a 'step-down' really. A 'step-down' from the 780 Ti would be a 780, and the R9 290 is about on par with a 780.

Also, 860w is a little on the low side for an overclocked system running dual 290x's. At full load, you'll be over 700w or more. Now, the AX860 is about as good as it comes quality wise, so you should be fine, just something to keep in mind.

I live in Sweden so with tax and all that crap there's actually a huge price difference. But about the psu are you suggesting that i ought to get an even bigger one, and if so, do you have any reccommendations.

Thanks for taking an interest

Ahh, that makes sense then lol well yeah, the $300 back in your pocket without taking a performance hit is awesome lol The 290x is a great card.

The EVGA SuperNOVA 1000G2 is usually priced well, though I'm not very familiar with Swedish pricing. 860w is generally perfect for a dual-GPU setup, but running dual 290x's at full load can really push up wattage.

SeaSonic and XFX both make great power supplies, so anything around 1000w would be what I recommend. Also check for Antec's High Current series, Cooler Master's V series, and Enermax's Galaxy and Revolution. All of those are solid, top-tier products.

What do you think of the Seasonic X-1050? I looked into the EVGA SuperNOVA 1000G2 and it's very nice, a bit more expensive, but really barely noticable. Does it have anything on the Seasonic though, because otherwise i'll probably go for the Seasonic.

Also i gotta thank you, not only can i get these PSUs from more reliable suppliers but they cost about 11dollars more (could be wrong, but that sounds like a pretty awesome deal to me)

The X-1050 would be perfect as well. Definitely a solidly built power supply :)

Awesome i'll be doing that then.

On a different note i hear that you need third party coolers to run even a single normal clocked 290x, what's your take on this?

The 290x's run VERY hot, and see noticeable throttling with the reference design coolers, which are not only poor at cooling the 290x, but also sound like a jet about to take off lol

Sapphire makes a great 290x that is cooled very well while being very quiet in the process. To get the most out of a 290x, I would definitely get a custom cooled card. The best solution would be to get the cheapest 290x you can find, and get the NZXT Kraken G10 with an Asetek-based AIO water cooler to keep it as cool as possible, but that adds around $100 to the overall price of the card.

Haha alright. I got (understood) the kraken G10 but i'm a little confused about the 'Asetek-based AIO water cooler'. Also would i be able to hook these parts up to a custom water loop in the future?

Asetek-based just means the AIO was built by Asetek. 'Generally', these are the rounded-looking CPU blocks, like the Corsair H50, compared to the square-looking CPU blocks like the Corsair H60.

And yes, all of those would be able to be hooked up to a custom loop in the future. That's definitely a better solution than an AIO route, but also considerable more expensive, as the CPU/GPU blocks alone are usually over $100.

Ok, i'm hanging with.

So the kraken g10 is a bracket which allows you to connect a AIO CPU cooler to a GPU, yes?

Yeah, and it includes a fan on it as well to help cool the VRMs, too. I would just double check that the cooler/card are compatible before buying anything if you do decide to go that route, as not all GPUs are compatible.

Great, assuming all goes well this will be my choice, especially if i can transfer into a full blown water loop if need be.

Just one last question, you said that a water loop would be much more expensive as the blocks alone would cost more than 100dollars. Would the part of whatever AIO cooler i mount in the brace be a GPU block in a water loop?

The AMD R9 290X is listed in the compatible parts and i'll just pick a cooler that is compatible

"Kraken G10 är kompatibel med en stor mängd grafikkort av referensdesign och kan användas ihop med nedan kylare från olika tillverkare.

Nvidia : GTX 780, 770, 760, Titan, 680, 670, 660Ti, 580, 570, 560Ti, 560, 560SE
AMD : R9 290X, 290, 280X, 280, 270X, 270 HD7970, 7950*, 7870, 7850, 6970, 6950, 6870, 6850, 6790, 6770, 5870, 5850, 5830

Passande kylare:
NZXT : Kraken X60, Kraken X40
Corsair : H110, H90 , H55 , H50
Antec : KUHLER H2O 920V4, KUHLER H2O 620V4, KUHLER H2O 920, KUHLER H2O 620

Thanks a lot for your help so far

I believe one of the Cooler Master ones is expandable, and you could buy 2 of them and tie them to the CPU and GPU together, but I am in no way familiar with that setup, and therefore don't want to say whether that's a good solution or not lol

The difference between air cooling a 290x and AIO cooling it is massive, though the difference between an AIO cooler and a full loop isn't nearly as big of a step.

Corsair H90 + NZXT G10 = $110 US
Custom loop (GPU alone - tubing, block, radiator, fans, pump): $300, which is general, as there is such a variation of parts you could use.

Haha alright, is there any point to tying the AIOs together or just to make it look better?

I'll probably stick with this setup until i decide i want those pimped out red tubes in my rig and then i'll cough up the cash.

Like I said, I really don't know much about tying the CM coolers together, and they're the only one I've seen that has that option. I'm assuming you'd get better temps, and water flow would be better, but I'm not really sure lol

But that sounds like a plan :)  my eventual plan is to get my 760s on SLI and then do a custom loop for the heck of it. But that's a waaaaaaays off lol

aright, i'll give it a try if i get those. Same story with me, get another 290x and crossfire it with custom water loop, but far off. Anyways thanks for your attention it's been really helpful and good luck with your SLI custom water loop!
