Hey guys!!

Let me start by telling you what time running first of

Asus M5A99X Evo R2.0
AMD FX8320 @4.6Ghz
Corsair H100i
Sapphire R9 290 Vapor-x
******** Workstation V2 Black Edition Bronze 850W
NZXT Phantom 530 - 8 Fans in total

If you need to know any more let me know ;-)

Q1: Ok basically with this motherboard i think its only got capable of x8 in crossfire is this correct? And if so, would i still see a nice performance % boost going crossfire? Is it worth it?

Q2: i currently have a single r9 290 vapor-x OC, now can i purchase a referance r9 290 and run the two cards in crossfire seems as they are
both r9 290's?

Q3: And would my power supply be enough to handle the 2 cards? Maybe enough to handle 2 r9 290 vapor x in crossfire? Along with the rest of my system,

Thanks for reading!!

P.s my first post here, so ello btw ;-) and sorry if this is in the wrong section >.<
 
No i wouldn't recommend it with your current CPU as scaling will put quite a lot more stress on the CPU and i really don't think it has the grunt to power two 290's i'm afraid! Everything else seems fine!

Lulz what a load of poop.

CPU is fine. I think I know what PSU that is...Oasis champagne...

You can mismatch cards but I wouldn't. Not sure that PSU is up to it.
 
Awh no way, so my fx 8320 would bottleneck the 2 290's is what your saying mate? Thanks for the fast reply btw!
 
Ahh right, i only have 1 24" 1080p monitor, so atm i think i play games like bf4 on 1920x1080 something like that
 
well if you wanting to run over 100fps some games can get a bit crazy on cpu usage
a lot these newer games are just not designed for it
but maybe bf4 is not so bad at it

i duno its up to u!
maybe jump in some bf4 benchmark threads to see if its worth it
 
tbh if your just playing BF4 @1080p on an R9 290 your probably using Mantle, there is absolutely no reason to add another card right now for BF4.

However if you are going to play other stuff, adding another Vapor-X is going to help, but i would upgrade the monitor to a 1440p screen and upgrade the PSU to a 1000w or so decent one like the Superflower Leadex Plat or Gold rated.

290's perform better at higher res as well, your CPU wont be an issue either
 
There might be a bit of theoretical bottlenecking but you'll still see a big jump in performance going xfire. I couldn't say for sure if that PSU would be up to the job though.

Didnt see his PSU, that could be a problem there for two 290s tho to be fair i remember matt getting away with 750 watt PSU with two 290X

And Yea maybe it is fine with one 290 that wasn't what i said. Two 290s will get bottlenecked!
OP will see a performance boost granted but will experience bottleneck and depending on game scaling might see it even more!



Also did you link me dying light with a nVidia GPU as bench? That game is optimized for nVidia for a start and isn't very optimized at best. Its dog poo!

I would say no, I tried 2x 290x on my Asus Crosshair and 8350 @ 4.7 and it wasnt pretty , the bottleneck wasnt the cpu but the pci bus (PCI 2 x8 + x8 )

My 3770k and z77 sabertooth was a better match but still far from perfect (PCI 3 x8 + x8) , still lots of crossfire related stutter , apparently the optimum platform for crossfire 290/x is either z79 or z99 where you can run it on a true 3.0 x16 by 16 , well dependent on the cpu anyway.

The fact is there isnt really anything wrong with AMD's 8 core FX range, its the platform thats very very dated

PCI 3.0 x8 is literally the equivalent of PCI 2.0 x16 so that shouldn't have caused a problem. My 295x2 is using PCI 2.0 x16 on the old Z77 and I've not seen any problems yet. I could use 3.0 if I got an Ivybridge CPU but I've yet to see a need and would rather wait for Cannonlake.

The 295x2 is a single card , my old AMD system runs a single 290x just fine without issue, its crossfire across different pci slots i'm talking about .

It's slanderous if it isn't true.

Modern games don't give a stuff what CPU you have.

And they'll continue to not care either.

All of them are within a margin of error.

I disagree. I'm heavily cpu bottlenecked in several titles with a 3570k at 4.5ghz with my 290s. Those titles could do with some optimisation (dying light, project cars) but the end fact is that I am better off playing with a single gpu due to the extra load my 2nd gpu incurs
 
Your CPU will be fine with crossfire 290s. I have an [email protected] and the scaling is fine, and there isn't too much stress on the CPU.

People really overplay the inadequacy of the 83xx series.

I do have PCIE3 x16 + x16, though.

All out balls to the wall your CPU is not as powerful as a FX 8. You will lose every time in Cinebench and other 8 threaded apps.

But that's besides the point, dude. The point I'm making is that see Dying Light? that's what you can expect from next gen games. And don't use the 8320 as a reference in that chart use the 9590 because all 8320s are easily overclocked.

The CPU race is over. Sure, in benchmarks and other 8 threaded apps the Intel owners can get out their blue willy and wave it all over the place. I'm not talking about that, though, I'm talking strictly about gaming.

The new consoles are coded to work with an 8 core AMD. Now obviously CPU core technology and threading needs to be added to the code before it's compiled for the PC but I have a distinct feeling they are leaving that CPU support in and that's why you are seeing AMDs do so well against the Intels.

Whatever the reason? there's no point in spending top money for a gaming CPU any more. It isn't just Dying Light either, look at any recently released game for the PC.

I have a 8320 and a 7990 and I can assure you there is no bottle necking going on. Sure, in certain older games my minimum FPS might not quite be up there with the Intels, but since when was 80 FPS min not good enough? (I refer to something like Shogun 2 where the Intel does 100FPS.. Loose example but you get my drift).

I also had 670 SLI with the same FX 8320 and again, the FPS and benchmark results at the time were excellent.
