In the meantime I'm waiting for to buy couple reasonably priced custom built R9 290X, hopefuly soon.

Maybe than I can find cgminer config that would allow me to use for mining only one card when gaming.

I still mine on some games at 12 to 14 intensity. Usually games get priority it seems, so 60fps is maintained. Because of that, the hash rate can fluctuate from 200 to 650 while playing games. I don't consider that pointless.

Will my psu be able to handle 2*"XFX Radeon R9 280X 3GB (Tahiti XTL)" crossfire not overclocked? Will use for light gaming (dota 2) and mining?

Wrong thread, but yes, if you're speaking about that 850w.

Thanks!

It seems like no one has an idea about the question above. Either that, or it was simply lost amongst other conversation.

Anyhow, let me pose a slightly different question. Knowing that I'm using a cut portion of the stock cooler as my VRM1 heatsink, would the Fujipoly Extreme (11w/mK) thermal pads work well for VRM1 cooling? Specifically, would it work better or worse than the stock gray strip padding?

Any opinions or facts on the matter? Thanks.

That concerns me too.

they can do over 60hz but only at 1100 or so core... which is really only a 100mhz loss in possible core clock since most 290/x's aren't stable over 1175-1225 anyway.

It is annoying though I agree as I am suffering this problem. It may be amd driver related and get fixed eventually...hopefully. Or it might even be an issue on the monitor pcb end since they are "overclocked"

lol you guys. I posted a detailed explanation awhile back on why for a single 290 you don't need more then a 650w psu . as long as it isn't a crap psu.

maybe my post could be added to the op somewhere because people keep asking the same questions and recommending overkill psu power.

See my post here with the math to back it up. http://www.overclock.net/t/1436497/official-amd-r9-290x-290-owners-club/11550#post_21421778

I want to add that getting a bigger psu can still make sense like you said in case newer cards use more power or you want to add a second card later. However to the other guy i'm not even hitting 475W usage on a 650W psu (with my heavily oc'ed cpu at 100% and oc'ed gpu at 100% and a water cooling loop)

so that isn't going to effect the life span on the unit at all. Remember too these are designed to handle up to their max output 24//7 and it's something of a myth in my opinion that running a (quality) psu at max capacity lowers it's life span.

I know, but not life span is the main thing, but I'm afraid that the newer cards will be still more power hungry, because there is a problem with lower manufacturing process (now 20nm) and it could happen with more power cards you will need stronger power supplies?
The price difference is 24 EUR.

Woohoo i'm back up and running everything is good and i have been benching. I added 2 more rads to my loop (phobia dual 200mm rads) it's overkill and all but my cards can barely reach 45C now on full load in benching. I'm just not sure about the WHQL 13.12 drivers yet.

Also, anyone know if there is more than one version of firestrike? I've seen videos and scores that don't match mine. Like the amount of tests are different.

I asked before and the consensus was that it is some kind of audio feature/function. Possibly True Audio?

Thanks for the info. Im gonna have to ask in the qnix thread if nvvidis shares the same issue.

Are you seeing the demo play first before the actual tests?
