is the 7990 best left at stock speed or overclocked via Amd Catalyst,
i've only got a 750 corsair on my other rig so i guess that i cant go too crazy

also does the Corsair CS750M have the right plug connections for this card, i think it's twice what my 7970 has ????

I'd run it at stock clocks and under volt it a bit to keep noise and temps down. However the first rule of owning a 7990 which is essential is flash the card to use my custom bios and rid the card of continuous throttling. See the guide here.

wow that looks way too complicated, i'm not sure about all of that, it looks too scary
 
I wouldn't advise overclocking it for gaming unless you have noise cancelling earphones.
Definitely whack the power to max though to prevent throttling.
 
ok i'll print that off, thanks for the effort you put in Matt
i want this card to run lazy as i'm only on 1080p.........but then again;) well you know how it goes..;)

what about the R9 290X ????? Yes, but the 7990 was too cheap to ignore ;)
less that the 290X

If you don't flash the bios then the card will throttle and performance will suffer a bit, but the choice is yours. Even with 20% power tune and the stock bios undervolted i still found it throttled on any sort of intense load.

If you follow the guide, you can't really go wrong. :)

ok m8, i've just printed it off
 
+1 for LtMatt's advice. I did exactly what he suggested.

Did try overclocking the card and it doesn't overclock much at all, probably not worth it in my opinion, I kept mine at stock and undervolted to 1125Mhz.
 
the 7990 card arrived today...........GREAT !!!

EXCEPT.........the brand new corsair 750w blew straight away, not even with a card inside the rig !!!.........it cost 25 quid to send it back to here

so fed up right now

i wont overclock because i'm only running a 750w psu, but i can still stop it throttling back, so i'll still try Matt's download

i doubt i'll get a replacement psu until friday...........unless i use the 1000 w one from my new rig
 
i can afford it, but i cant cancel the corsair CS750M RMA until they have the broken PSU in their hands..so maybe later tomorrow

that Corsair doesn't have the build quality of the BE-QUIET, the BE QUIET looks far superior... it also has better packaging as well .

Just looked online, yea that psu has quite a few faults
