Hello all :bounce: 

Okay i would like to get some things cleared up lol . Is it better to have one high-end card with 2 GPUS than having 2 cards in either Xfire\SLI with single GPUS !

reason why i ask is that are all games made to run with one Gpu rather than 2 ? so lets say if i was to get an AMD 7990 would i get better performance than using 2 cards with single gpus ? in some games I've noticed when using my current setup some of the games dropped fps once in Xfire but once turned off i get like 20% increase but not in all games just a few !

Just looking for some answers guys !

i hope this is as clear fully and understanding ! Thanks for reading and any reply s ! :)

Ah okay Thanks for the post ! always nice to get advice from other posters :)  I'm still going to get the 7990 as it's a lot better than my 2 Xfire 7870's ! but i just hope the card does not have much issues with heat !

I would really consider getting two high end cards instead of a dual GPU single card. For one if something happens to the 7990 you are out since it is a single card. If you got two 7950/7970's and one card goes bad you can still use your system with one card not so with the 7990.

Read this review of a 7990 with reference heatsink/fan. The 7990 when tested with Furmark stress tester was the hottest GPU ever hitting 90c. In BF3, it was also the hottest at 84c. It is also the loudest GPU due to the 3 fans. Even non-reference designs need the 3 fans. If there was a GPU that actually needed a liquid cooler it is this one.

But that doesn't necessarily mean you will have heat issues. Maybe just higher than average but not to the point that it will crash. If it does then you might want to consider something like this: http://www.frozencpu.com/products/19962/ex-blc-1453/EK_...


Thanks for the Review ! Noise is not an issue as you can Imagen am using Xfire 7980's and its a bit loud once i turn up the fans to say 60-70% !!!! i think i will still go got the 7990 even tho it heats up but i guess i could always look push towards WC both cpu and GPU next year for my first project !

The 5970 was recorded as running hotter although it was being OC'd in the article.
