Crossfire R9 290

[sgtsmokey]

I was going to wait for the R9 390X but I figured two R9 290s would have more raw power that 1 390x. I am right in thinking that aren't I? As I have just ordered my second R9 290 due to it being £100/$150 cheaper than when I first bought the R9 290 a year ago.

I know one card is more stable than two, but as far as power goes my two cards will over power one new generation card right?

I do know its going to bottleneck my 8320 fx cpu, but I order 5820k in January .

Then I say hold off the extra 290 till january

Seems fine, just as long as you are aware that you may need to wait for AMD to give you drivers with Crossfire profiles. (I have to do the same)

2 290's will be faster than a 390x. If you go from 1 to 2 cards you get mostly an 80% boost in games if the cpu doesn't bottleneck. There are of course exeptions, sometimes crossfire doesn't work or causes microstuttering.

shoooooould be fine.

 

make sure you use mantle whenever possible to alleviate that CPU bottleneck.

A little bottlenecking is just going to restrict my fps, but increase performance overall. Waiting until January to go cross fire isnt going to cause any damage at all when my cpu doesnt go over 45c under full load .

Adding the cpu in January will just increase those fps more that is all.

Very true. I have 2 280's and its very buggy. At stock its fine but OC crashes....... :angry:

Probably the fault of the gpu's. I have actually the opposite. I have 6950's that are flashes to 6970's and when i try them alone 1 of them is unstable and causes weird crap. If i put them in crossfire, no problem! It's partially a case of having luck tbh...

Luck is right, my first 280 is pretty descent and the second is unstable, wont clock as high. But at stock they scale very good, better than my 760's. Valley benchmark is 3266 extreme HD

My R9 290's are both stock clock 947mhz Gigabyte Windforce Editions. I know most people would buy my card for overclocking due to the 450watt cooler, but all i want is cool and quiet gaming. Under load 1 card has never gone over 74c, having two might increase that a little but I don't like overclocking. I just prefer to buy a better card or two, if a better card is available.

Although I do plan on overclocking my 8320 fx just before my second card arrives so i can make the most of two cards until i upgrade the CPU
