Hello,

you really need 2 right off the bat? you have 2 6950s? one of these is roughly equivalent to 4 6950s. if you are watercooling i suggest you look for a reference 290. i suggest a MSI.

Buying now for a little more time, so let's get find.
Is MSI better than Sapphire.
Whether all R9 290x have dual bios?

All of the reference ones will be good, but MSI does deal with serial # for warranty, which is very nice.

Yes all of the reference R9 290X have a quiet mode and uber mode, while the R9 290s (non-X) have the same BIOS on either switch.

for reference, they are all the same. if you get one of those non-reference, you run the risk of having one not matching the block. you'll break your warranty if you mess with the stock cooler with the sapphire.

if you are a bencher, then get the 290X. if just for gaming, then the 290. it's silicon lottery whether you get a good clocker or not. oc the 290 50MHz and it should match the X.

make sure you have enough juice. I recommend 850W minimum. and . . . oc that cpu.

that is perfect. go reference and watercool.

btw, you've got a beautiful rig. if you'll use an ek block i recommend using this for the vrms . . .

more than enough for 2 blocks. even 4. not sure what paste you have but the Gelid extreme is good for the core.

Thanks for informations.
From picture is my old rig, I'm currently working on a new rig.
See picture smile.gif.

Today I buy two Sapphire R9 290x and two waterblock EKWB.
Is it possible to be such a big difference in temperature to thermal pada?
I'm from Croatia, shipping and article cost me over 30$ and I must wait min two weeks.
Does it really worth it ?
Do you have that European store that sells items listed?
