Just making sure you didn't get the yellow text of death on your sig ;)

Ah, watercooled, thanks for letting me know. I want two at that price but I don't wish to WC them. I have heard negative stories about temps
 
Thanks LtMatt muchly h'appreciated. I never did get the hang of evga precision wish it were like the old days 4 and 5 series NVidia nice n easy :)
 
Hi all, 1st post. Been reading this thread with interest. I bought 7990 when frame pacing drivers and price drop made it a good deal. I did order the lower spec one from scam but they sent me the higher specced VTX card. By mistake or coz they didnt have any lower priced ones left I dunno. This was before branded cards were below £600 other wise I'd have gone for the £499 MSI.


My rig runs a sandy 2500k at 4.4Ghz an old 650W Antec true power trio with 6 pin PCI-E with 8 pin adapters. AND I'm running it in PCI-E 2.0 as difference was 1% from what I read. So far very pleased with performance at 1920x1200. Both cores will run at 100%/boosting when playing Crysis 3. BF3 and Crysis 3 have been very smooth though I never experience xfire microstutter as I never ran pre 13.8 drivers.

Idle 38 degrees and load high 80's. The ASIC quality isnt great and was wondering what other owners had in ASIC quality. Mine is 63% and 66% respectively. I was wondering if the branded cards has higher ASIC quality thus better OC'ers. Not OC'd mine yet as little point in what I'm losing a bit through PCI-E 2.0. Any views on whether my PCI-E 2.o would be bottlenecking though the card boosts in Crysis 3 so I thought not. I know I may lose 1% from what I have read in PCI-E 2 vs 3 reviews.

Thanks in advance

Going from PCIE 2.0 to 3.0 with a dual card solution isn't bringing much performance penalty. You loose 1-2 FPS at max at your current resolution of 1920x1200.
 
Asic quality is very subjective. Some of the best clockers are at the 60% territory, and others at the 90% territory. Do not worry about it.

You will not miss anything with PCI-E 2.0 x16 vs 3.0. Don't worry about that either :P

However, your 650W PSU will be at it's limit on your system, since you have also OC'd your CPU. Running at max load is not a problem of course, it will wear out your PSU quicker and make it noisier, but as it's a decent quality one, you'll probably run fine for years.
 
Thanks for your replies. My PSU is already 7 years old and was good performance/value at the time but probably in terms of efficiency ratings (bronze, silver, gold, platinum), make a 'cast iron' rating for efficiency. By no means was it a true 'performance' PSU.

A new one is on my shopping list but like anything - if it aint broke. I was told that PSU's are better if they run in the top 20% of their rating for Watts by a well informed freind.

I DL's the Uningine valley benchhmark last night but unfortunately my res is difficult to make a comparison. If I select a different resolution e.g. 1920x1080 from the list will it bench it as that res or does my monitor have to be the resolution required.? Do I run it at Extreme HD and 8x AA for single monitor? I did look for the settings but it only lists actuals for the multi monitor set up. Sorry for the noob questions.

Best

Scrub the Q above. Didnt realise the Extreme HD preset defualted to 1080. Ran it and at stock - I scored 78.0 in Valley so pleased I'm in the ballpark with other 7990's.
 
So...is everyone a happy 7990 owner with Mantle announced? Certainly looking to see how much further this thing will stretch its legs in the future! Plus nothing announced to best it ;)

Certainly, even the new AMD cards (even with Mantle) won't touch the 7990 with 2x7970 cores and at sub £500. WOW.... (although I did get mine the day they were released at £840, but had months of a 7990 before the drop)

My brother lives in Holland and apparently you can get Club3D's reference 7990 for just under £400. Worth going for? Also, any idea if I could just order it to his place, then have him bring it over for me with no trouble from the tax man?

Yes you could do that without a problem. it's Europe, not the US.
