I purchased 2x 270x and 1x 280x with 1x 290x. In all of the games and benchmarks I've tested I achieve greater results with the 2x 270x in crossfire. Even to the point where in Battlefield 4 I can get 87FPS with the 270's and only 63FPS on the 290x.

The 270x x2 is still cheaper than even 1x 280x and a lot cheaper than the 290x. You won't have to upgrade for years. (Even the power draw isn't a lot).

Please explain to me why everyone is saying to go with a 280x and or 290x before I sell these.

(I build and sell regularly as a hobby. I'm keeping the 2x 270x build.)

Thanks.

enjoy your microstutter and dropped frames then :)
personally not a fan of it, had both sli and crossfire rigs, will not go back to a multi card setup, single card feels much smoother when you compare the two systems side-by-side, regardless of the fps fraps records.

my experience with crossfire and sli. first started with 6600gt's back in the day. great bang for the buck. bought one for $120, bought another for $100 when i had the cash. great experience and i saw instant performance gains much faster than a $300 videocard at the time. I was told time and time again to get 6800gt's because of longevity and to sli them later. they were way outside my price point, and still were after i decided to switch from my 6600gt sli set up and onto something faster.

fast forward to more recent...i have a radeon hd7770. thought a xfire set up would work great. installed it, probably got 10 more fps. paid $150 for my first, and then $100 for my second...not happy at all. i ended up taking out the 7770 and putting it in a lanbox because for a single card it works great for a mid range videogame card. but xfire was just disappointing and baby-punching worthy. different chipsets and different architectures make all the difference in the world if it is "worth it". buying a single card vs. sli/xfire setup has its pros and cons as explained by many. but i will never EVER buy a top end card due to the depreciation. $400 one minute, $200 the next, and next thing you know you see it at a garage sale for $10. at least with my mid range to high cards, you wont see my cards depreciate more than half in a years time.

Tweaktown shows that the r9 270x in crossfire does perform very well, but they note that their are some problems with crossfire. it will never be perfect. but you will get better performance from a pair of 270x's than a 290x currently and for the price its worth it. just realize when its time to upgrade its time to swap all of it out. this is all from what i can tell, and not what i have seen or done.

If you have a 270x already, buy another 270x, next year when the R9 300 series comes out, upgrade to crossfire 370x or 380x...simple!

I have a new i7 4770, Gigabyte mobo (Z87 chipset), 16GB RAM and one (1) Sapphire R9 270x GPU.

I can run BF4 on Ultra in 32 and 48 player servers all day and average 60 fps+. It rarely drops below 60 and when it does, it stays in the 50's so, as of today, I am not looking to crossfire because I can currently achieve Ultra on my 22" monitor. I you want to go big screen or multiple and you must have Ultra settings, you will need to crossfire the bigger cards which might also mean you are looking for a solution that you cannot afford at today's prices.

Your fps may vary slight because it does depend on your box in totality.

Always remember that if you are looking to cross fire, you shouldn't wait too long or you will find that the GPU will disappear from the marketplace in a hurry. That's my plan anyway - wait another 6-12 month and then pick up a second 270x on the cheap(er).

@ATI7000

I´m going to answer based on my personal experience. I had Xfire setup on a MSI Z87G43 (R9280X+7970 Ghz edition) and in Battlefield 4 @5760x1080 60 Hz (graphics set to high with no AA) I was doing 65-120 FPS. When I was using just the 7970 I had the game running between 45-70 FPS. I want to add the fact that the MSI G43 board is PCIe 3.0+PCIe2.0 so basically the same ground as you :)

When I changed to the MSI Z87 G45 (with 2x PCIe 3.0 - thus xfiring @8x8x) I didn´t notice any huge FPS improvement BUT the gameplay felt waaaaaaay smoother! Well, graphically wise I set a few Ultras (mesh quality and postprocessing) and I run FPSs a bit higher - from 70-140). I would almost say you don´t even need a second GPU but probably you really want to set it all the way to Ultra, and I understand that :) If you can spend the money and you can´t settle for "second best choices" well, get a mobo with at least 2 PCIe 3.0 slots. If you´re slightly on a budget, snap out of it xD

I´m not the one to tell you to "snap out of it" because I did exactly the opposite!

Might be so late but still like to say im completely agree with forge and about this never ending question! It all depends on what's your needs and what are you looking for
I have same cross of two R9 270X sapphire dual x-oc and more heat , more noise and .... Aren't problem for me and i believe there might be some game's witch don't work properly with cross (unfortunately like COD Ghost) but more than cheaper price compare to 290 i think there are lots of abilities and in near future there wont be any problem with some specific games
Anyway cross rules and i should tell you befor my new cross i had cross of two 5850 sapphire toxic and i was always satisfied
Also more than yore cards for best performance you should care for adjustment of other parts such as cpu - ram - mainboard
At last good luck with your cards and enjoy the ride

Yes, that will work even if you buy a 280x you can put it in CF with the 270x.

If you put 2 different CF cards in CF your system takes the weakest one x 2 :)
2 different company`s is not a problem.

You cannot crossfire a 280x with a 270x, that will not work.

I'm presuming your r9 270x has 2gb memory.As newer games get released the r9 270x with only 2gb memory will get left behind .For example try playing Dead rising 3 with 2gb at 1080p . The r9 270x is not aimed at the high end of the market .It will be fine with most titles released up to now but its far from future proof .Even adding another in crossfire it only shares the 2gb memory so you will have the gpu speed without the resources .Games such as battlefield series are fine on this kind of rig. If that's all you intend to use it for there's no need to upgrade .If you want to be able to play the newest releases in all there glory then you have to consider one of the big cards with 3 or 4gb .
Just like everything else tech gets faster better and sometimes you might have to evolve to get the best.

No problems at all.

man, i dont think you was correct there!! I saw comparison between r9 290 (not x) and r9 390x and it was really not far behind. So it made me believe that xFire r9 270x can actually compare to the r9 390x. Maybe even be better for 1080p . Im pretty sure you already have 2 r9 270x's since you made this comparison. Can you please tell me if you are able to play QHD or 4k games with this combo? THank you 😉

theres a good amount of difference between the 290, 390 and 390x respectively, not huge, but enough but can be game dependant. The fact that the 270x only has 2gb ram makes it useless for 4k or even 1440p, unless you want to run lowest in-game settings to coserve vram. Anywho if you want to diuscuss it, just open a new thread rather than replying to this old one that already has a best answer.
