So I'm deciding between both of these monstrous cards :)
Right now my system runs this:
PSU = ENERMAX Platimax EPM1200EWT (1200Watt)
Case = Cooler Master HAF XB EVO
Motherboard = Sabertooth 990FX R2.0
CPU = FX-8350 4.7Ghz stable at 1.425 - 1.45 Vcore
CPU Cooler = Noctua NH-U14 1 x 140MM
GPU = XFX Black Edition R9 280X Core = 1080Mhz Memory = 1500Mhz (underclocked memory)
RAM - 1x8gb AMD Radeon Memory 1600Mhz CAS = 9-9-9-28
DVD-ROM = Asus DRW-24B1ST/BLK/B/AS
2x140MM B-gears blaster 110 CFM
1x120MM B-gears blaster 110 CFM
2x80MM B-gears blaster 70 CFM
SSD = Samsung 840 EVO 500GB (Write avg = 520 mb/s Read avg = 490 mb/s)
TV = 40 Inch Samsung 1080P 60Hz
Games = Watch Dogs, Space Engineers, Deus Ex: Human Revolution, Starcraft 2, Red Faction:Armageddon.

And my problem is that this card seems to have trouble at stock settings and so i'm going to return it for one of these because the price difference is definitely worth it and because I feel I got jipped that I'm HAVE to underclock to keep it stable. I'm having trouble between the two because I really love my all AMD system but, it seems these guys are neck and neck, of course disregarding games that favor CUDA or Stream Processors over one another. Anyways I really would appreciate any feedback as i'm making my decision over the weekend and I really want to make a solid choice and go with it.

Right now I'm leaning towards the R9 HIS because of memory bandwidth and amount of Vram.

Again any and all help appreciative.
(P.S. Ambient Temp = 24-27C (76-80F) and case is overall at around the same temp. CPU and GPU Idle around 38C-41C or 96-102F But, the videocard gets super hot in gaming i.e. = hitting 65-70C or 149-158F) Monitoring Software = HWmonitor, MSI Afterburner, Furmark, Prime95.
 
It depends on the price difference. If the R9 290 is significantly cheaper than the GTX 780, i would choose the R9 290.
Both R9 290 and GTX 780 trade blows in performance at 1080p. At higher resolution, the R9 290 will edge ahead.
If you prefer Nvidia's shadowplay and Physx, then the GTX 780 is an option. Either way, it depends on what games you want to play and if you care for Physx or shadowplay.

Thanks for the reply!
The reason why I have these two up here is because their's really just a 20-40$ difference here, the R9 290 being cheaper though. Cuda cores though vs Streamers I wasn't too worried about I just want the best overall performance, but, for instance if I get a 1440p or 4k monitor/TV in the future the R9 290X will perform better than GTX 780 by a long shot? But, really unless these cards really are neck and neck I really just want the card that's overall better and preferably the one with the better cooling as well, even though I do have a wind tunnel :)

Again any and all help appreciated :)

Well When I ran Furmark whenever the card hit 76C it started to artifact and even though the clock speeds never dropped (I maxed out the power limiter) The frames went from 65 to 28-32. As far as i'm concerned thats not really supposed to happen and I notice in games as well, it really destroy's the experience of whatever I'm trying to do.

Update: I understand what you guy's are saying I wasn't trying to be hardheaded or anything, I guess I'm just expecting there to be more issues and things to look out for than just CUDA vs Stream Processors. Also, I found out recently MSI makes an R9 280X that runs 6GB of Vram and it's on sale right now for 300$ flat (Newegg, holy crap) and that's cheaper than what I paid for this so I'm just going to save the money for a sound card and ram.
Also, should I close this thread since I have made my mind up? Or should I leave it open so others could benefit from the info?
