Changing GTX 580 for AMD 6990 is it worth?

Hi. I`m going to change my gtx 580 for a AMD 6990. I wonder is it a good card for Battlefield 3. I know that bf3 had many problems with crossfire. Maby they was solved with new catalyst or bf3 update. I want to play smooth on ULTRA settings and 1080p. GTX 580 can`t handle BF3 on ULTRA settings with 50+ FPS.

 

I would wait for the HD7990. It will come out in March.

 

Mine can?

Just don't use MSAA as its a modern engine and MSAA is unfortunately going the way of the dodo as it devours too much performance for very little gain with how newer engines are designed.

Stick with FXAA and maybe start to accept that's going to be the norm going forward.

 

I know, but i don`t wont to wait for next gen of dual gpu`s. I can replace gtx 580 for radeon 6990 with almost the same price. So tell me guys is it worth to do that mostly for BF3 at the time.

 

Sounds like something else is going wrong with your computer,I've got a 580 GTX and i run BF3 on ultra with between 55fps and 60 fps!

 

not true. Try to do some mess and you will see drop of fps nearly 30 wich is unplayable for me ecpecially in this game.

 

Nope, not for me.

As I say just don't use MSAA.

 

Anyway. Guys. Please tell me is it worth to change GTX 580 for AMD 6990 at all?

 

6990 have beter performance and vram
idk how it works in batlefield but every game must work on any gpu (1)
check some benchmarks...

 

The 6990 has alot more firepower than the gtx 580 but i still can't believe that your GTX 580 doesn't handle BF3 very well...I didn't play multiplayer only for a bit and did not record my fps but in single player i can tell you for sure that my fps didn't go below 45-50 FPS no matter what i did (explosions,grenades,smoke etc) and thats with a gtx 570 on 1920x1080 with everything on including MSAA 4x ...oh and that was with my old CPU a phenom II x3 OCed at 3.6 ghz...altough not sure how much of a bottleneck it was in single player.

So in short no its not worth to change your card to a 6990 if you game at 1920x1080/1200...your GTX 580 should handle every game you throw at it at that res at nice fps. Check your Task Manager and end unnecessary programs running in the background that use too much CPU...that might be it.

 

Not sure why you're not getting at least 60fps as the GTX580 is pretty fast for a single GPU but for games like BF3 settings do matter and if you put up AA it will drastically lower your frame rates at the cost with little difference in image quality. I myself run the game at 1920x1080 @Ultra/FXAA/16x. I turned off MSAA and I get average of 55+fps, majority of the time 60 and occasionally dips down to 40ish if there is a lot of explosion on the screen. Though there is a chance that the RAM on the card is whats slowing down the performance if settings uses more than the amount of ram (1.5GB). So based on resolution and quality settings, yes it can use more than 1.5GB and that is where the 580 lacks.

As for 6990, yes it will be fast, you're going to get high frame rates but you have to get the right working drivers as well as tinker around with some settings. My bro does have a 6990 on a 120Hz monitor and I can say that it runs really smooth on his rig without any slowdowns. On the other hand games like Skyrim or games that aren't optimized for crossfire you may see some flickering or graphical issues and its not always that you can turn off crossfire because the 6990 is two gpus in one.

But in all actually its pretty much like this in performance:
GTX580 > HD6970

HD6990 = 2x HD6970
HD6990 > GTX580

Not trying to scare you but if the game and driver supports the particular game, you will have no problems, best/fast experience. But if the game is coded badly and the drivers aren't up to par with the game then it could be a nightmare experience. Example with that would be Skyrim. On the 6990 it will run crazy 200+fps, but you get occasional flickering and other stuff, there may be workaround on those but havent really read up on it. But there were occasion where the 6990 was getting negative scaling which resulted in worse performance than one HD6970 that was when the game first came out and it took them a few weeks to release working drivers. Not sure how the drivers are now on the nVidia side but AMD side could use some work. This is more of a headsup rather, so if it doesn't concern you too much then you wont have many problems.

Here is a benchmark to get rough values. Wont take it to heart but its something to expect.

 

If you've got the money, and a little patience(required for all crossfire users), then go for it..a 6990 would be around atleast 50% faster than your 580 in games that support crossfire properly..i can play bf3 on ultra with everything turned up and maintain atleast 60fps...and yes bf3 is working flawlessly for atleast me..using the latest 12.1 + asder caps

 

but doesn't the 6000 series choke once you enabled MSAA so may end up with worst performance in BF3 with 6990 than 580 with MSAA x4 enabled ^

 

getting a 6990 is silly now that 7970 is out...the vram itself will become a huge deal

 

Get another GTX 580 for SLi if you can, I'm sure you would be more happy with the performance compared to an HD 6990.

Reason being is that ATi/AMD cards struggle more with MSAA on BF3 compared to Nvidia cards and there's typically more issues with Crossfire than SLi.

As for people claiming that a single GTX 580 can handle BF3 at 1920x1080 4XMSAA Ultra settings with a minimum frame rate of 60 FPS...that's false.

Every review site shows the GTX 580 averaging 43 to 57 FPS with a minimum of 31 to 47 FPS. Granted these are benched on the single-player, the multi-player is more demanding.

 

Sorry mate you´re wrong. 4XMSAA or whatever you use at this moment on BF3 won´t make a GTX580 run faster than a HD6990 with the latest drivers.

On the other hand I would wait a few days now that HD7970 are out and performing close/cheaper and not eventually CFX problems imo.

 

Let me just say that with my 6000x1080 I hate my GTX 580's all 3 suck and I cant wait to get rid of them. I run out of Vram in most any game worth playing but playing with 1 screen sucks and I'm not going back to that now.
The 7970's cant come out fast enough!

 

So. For almost the same price i`ll go for HD 6990. Good choice? 6990 is alot faster than 7970 and price in my country is about 800-900 bucks. Now i can take 6990 for 500. So?? What do you think guys??

 

I would suggest to wait for a new card... Because single card is always more trouble free.

 

you can wait two weeks only and buy a 7970 for 500 bucks

wrong !!!!!
