this is R9 290X or R9 290C????
212939
This is just the R9 290 the "X" version is 1GHz, this is 947MHz... but other than that exactly the same card.

I'm not sure what the R9 290C is, but I've never heard of it as of yet. This is the Hawaii Pro version of AMD's new cards, so second from the top. That's evidenced by the 947MHz maximum clock speed and the thorough lack of x anywhere that 290 is written...

when it was purchased? How long usage? did you make overclock the card? Do you know if this card is unlocked to 290x?did you make Flashed Bios? Displays black screen?Why the sale?Qual o modelo? (XFX R9290AENFC) ?

I use the Asus R290X DirectCU II card. Yes it was $600 but with Mantel enabled it runs BF4 on Ultra at 1440p with no problems at all online with 64 player servers. Not to mention the same brand card that Asus makes for the GTX 780Ti is about $100 or so more. I'm very happy with the graphics card though, it runs very cool with the Asus DirectCU and has no throttling at all. Its quiet as heck in the Uber mode compared to the stock 290/290X cooled cards. Those cards even throttle in Uber mode and are so loud.

The lightning cooler is fantastic, so coupled with the 290x, you should have a very fast card (290x is faster than the 780 and on par with the 780Ti) that runs very cool.I do not have any experience with the Asus Matrix Platinum 780Ti, so I cannot comment on that one.

I haven't gotten this card yet, but is my planned next upgrade from the r9 280x (xfx). But I will say what I've found in my research. Direct competitor of this card from Nvidia it seems is the GTX 780. very close. http://www.pcpro.co.uk/reviews/graphics-cards/386182/amd-radeon-r9-290x-vs-nvidia-geforce-gtx-780 (it's not about the sapphire version but it is about the 290x) check out gpuboss for some comparisons & tom's hardware for reviews. From waht I've read specifically to the vapor x version of cards, it is actualy cheaper than the toxic version, is only slightly slower, and rumored to be cooler.

The price does not justify the means. There are overclocking tools now that make it so easy. Buy the normal version, use msi afterburner to overclock the clocks as the SC version and never look back. They are the exact same card.

280x will be fine. there is a difference between 280 and 280x though, 280x is better fyi. 290x is kinda expensive, but the best ati has to offer

I'm afraid I have no information or insight into the differences between these two cards. The appear to be interchangeable. Who knows - they might have come out of the same factory....

If you want a quiet or cool card stay far away from the AMD R9 series. The reference R9 290x sounds like a leaf blower sometimes when I would game with eyefinity. I ended up selling it for a GTX 970.

I believe the 2900 is 440 watts and has 10 year warranty vs. 3900 is 600 watts and 5 year warranty.

I have 2 of these and they work wonders. Depends what you're doing/playing. If you're monitor is 120/144hZ or 4k (best to go with the 4gb version of this card) What are your specs going to be?

at the most the 750 TI SC should hit 55 - 60c tops, it all depends on what boost clock the card is capable of, some have mentioned hitting 1300+ if you are lucky.

750 Watt should be plenty!!! You may have a bad power supply and it may need to be replaced that happened to be before. I have an tx 850 corsair power supply and I run 2 of the r9 290x crossfire, 2 ssd, 3 hard drives, i5 2500k oc 4.7 ghz, sound card and a ton of other stuff. Hope this helps

not sure by model number how ever this card is a non reference pcb style gpu if you want to know then you should contact sapphire at their website of www.sapphiretech.com i could not find it my self though

A 270 x is basically a 270 over clocked. Basically paying more money for a card when you can just download MSI afterburner and over clock the card yourself. Which is what I did. I got a 290 instead of a 290 x and saved myself over a 100 bucks at the time. Then I just boosted the core and memory clock myself and it performs on par with the 290x.

I'm not sure an r9 290x has the horsepower to drive that many monitors. A 2k monitor takes about 1.5 to 2 gigs of VRAM to drive, and the reference 290x has only 4 gigs. Without sufficient VRAM the regular ddr3 ram is utilized which is much slower than GDDR5. And no crossfiring 2 cards doesn't double the effective amount of VRAM, only the computational workload is shared between GPUs, the second cards VRAM isn't utilized in crossfire for display driving. I would look at non-reference cards and see if one is made that can support your needs.

In this case I'd say 780 To is the fastest overall. The r9 290x is second and 780 lightning comes last. However just keep in mind that all 3 are more than capable of handling anything being thrown at them at 1080p. Also the r9 290x will handle higher resolutions better overall dye to its higher vram

Gigabyte 6670 doesn't exist I'm guessing it is Raedon HD6670 that you are referring to and yes this card is slightly better than that according to: http://www.videocardbenchmark.net/compare.php?cmp[]=1432&cmp[]=96
