7990 or 690?

[GodsPrototype]

I am thinking of getting a new GPU, as mine is a bit old and I want to play on all 3 of my monitors. Let me start off by saying that SLI or Crossfire is not an option, because i have no room left on my motherboard.

 

So, the 7990 is my first choice, because it has 6gb of mem, its the faster card of both options, and it's also the cheaper option. However, many people have told me to get the 690, without a reason. I am wondering why this is. Which would you get? I don't play any PhysX games, I am planning to only play DCS, Arma III and BF4.

 

So... 7990 or 690, and please give a valid reason why. Plus, could you also suggest to me which one to exactly buy, as in manufacture (ex. EVGA, Sapphire, MSI etc.)

 

Thanks in advance!

7990 is a Crossfire GPU, there's 2 GPU's on one PCB, and they each have their own 3GB Bank of Ram.

 

690 is SLI, Has a 2GB Bank of RAM for each GPU,

 

if you want to run multiple monitors, the more VRAM the better.

 

Since IM an AMD Fanboy, go with the 7990, just make sure you use the latest Frame Pacing Drivers.

Yeah I heard of the new drivers and they sound good. I'm not a fanboy of either, but I have to say that I'm leaning towards the 7990, and as you mentioned, it will be better for higher res and multi monitors.

 

Since you are a AMD fanboy, could you suggest as to what 7990 to get. Like Sapphire, MSI, Powercolor? Thanks!

[SkateZilla]

they are all the same reference design (except power colors),

 

Pick the one with the best warranty.

Ok thank you very much!

Crossfire is of little advantage in DCS. There have to my knowledge no reported cases of successful crossfire utilization in DCS with substantive facts. the 7990 and 690 are both dual gpu so they are basically crossfire/SLI on a single card. Also even though the 7990 has dual 3GB vram you dont really leverage more than a single core's memory. The same applies to the 690's dual 2GB vRAM. I dont think 2-3GB vram is really enough for 3 monitors at high settings without incurring a performance hit. I currently use 1.9GB with my 6970 at 1920x1840

I have been a long time ATI user and have literally just bought a 770GTX after being frustrated by AMDs drivers. My 770GTX is a 4GB model and will be here wednesday.

 

allegedly DCS performs better on Nvidia vs ATI and so does FSX if your into that. It also appears that SLI does work with DCS ...read about it here

Well actually that is not totally true. I also thought that at first, which is also why I wanted to buy a 4gb GPU, but both the 690 and 7990s architecture allow it to use its total amount of VRAM.

I don't think i was specific enough...each core can only access 3GB/2GB respectively. Since each GPU is rendering a full screen. So if for example a frame requires 3.2GB of Vram for rendering you will have to go to system ram as each core cannot access more than its 3Gb/2GB limit

Both 6990 and 690 are obsolete. Buy titan or 780GTX. The power of 2 GPU's without crossfire or SLi hassle.

Or AMD equivalent.

 

Agree though, avoid using CF or SLI in DCS at all costs.

(be it 2 cpu's on the same cart or 2 physical cards)

[SkateZilla]

the Titan does not have the power of 2 GPUs..... 1.5 to 1.75 maybe...

 

If they ever get decent fabs of the GK110 with all the SMX's healthy, then maybe, but that will never happen.

The AMD 9900 series is rumored to be launched in October. With the 9970 being faster than 780 but slower than titan.

the 9970 is faster than the titan on paper.

I have stayed with AMD since they came out with eyefinity. I never looked at nvidia because of this.

 

I have been reasonably happy but at the same time I know that most sims prefer nvidia. eyefinity is no longer a biggie for me, its supported with nvidia.

 

I know some things have much better performance with nvidia, e.g. xplane. Things like AA shimmering are better on nvidia with fsx, xplane. I have heard the picture quality is better on DCS with nvidia.

 

My next card will be an nvidia because all said and done they seem to give a better experience on flight simulators.

Before i had a monster of a 5850 1 GB :D, BUT i did run 3 monitors on it at 5760x1080 in iRacing and it performed very well there. DCS though is a totally different matter. Anyway guess you should go with a newer Nvidia for DCS as said by others. Always liked AMD before and still have one in my other PC. Nvidia and AMD always also gave a different picture regarding colors. But am happy with my 780. It IS too much money for a card i think, but i had to make sure if i bought one it was good enough. hopefully it will grow even a little more when i get a newer CPU.

9900 series in October is still along way off, if the guy is pulling the trigger better do it now because as I see it the performance difference (being between the 780 and the titan) is just not worth the wait.

 

Also, don't NVIDIA's run DCS better than AMD's?

same here. Until I ordered my 770GTX on sunday my last Nvidia card was a 8800GTX. My current card is a 6970

770 is a great card for the price....if your rich get something better (780 or Titan)....

 

i personally buy in the 60s.......260s, 460, and now the 760s....but I own Asus and EVGA SLI boards...so its hard for me to buy two $500 cards because I'm poor, but two $250 evga 760 is bad ass in a SLI board....there is no game out as of right now (8/6/13) that Sli 760s wont run....stacking bigger cards is for ppl with money to burn and those that want outrageous benchmarking numbers.....

 

....Nvidia all the way....I'll never go back.....and I always buy EVGA.....

^^^ EVGA760 /w ACX cooler $250usd^^^^^

^^not a bad price considering I remember spending $400 for 2 gtx260's ($200 each) just a couple years ago....those 760s are ten times the cards for just $100 more^^^

 

 

P.S. stacking cards becomes very beneficial once you need more then two DVI ports

I go with bigger cards as I dont rely on DGPU/SLI/Crossfire cards. They dont work with everything I fly

So what about a GTX Titan 6gb. It's a single GPU with 6gb that means I would be able to use all the 6gb, so that would be good for my multi monitor setup right?

 

I'm eager to buy a new GPU because I just got my salary of my summer job and I got birthday money from yesterday. So price is not really an issue unless it goes higher than a 1000 EUROS! not dollars. I can order from Amazon though, so that will save me some money.

What about the rest of your system? Something there which could be a bottleneck? Better make sure you have the power to make use of a Titan.

Then that should be sorted :D

[SkateZilla]

You can Get a 7990 for as low as $650 if you look at new egg close enough.

 

AMD Just dropped them to $699.

...or a GTX 780 from Amazon for the same money.
