Pros: Great, forget when i bought this but it's been a few months at least. Still rocking and my cpu (fx 8350) bottlenecks this thing about 80% of the time.
Other Thoughts: Over clocks alright, mines litecoin at about 400 kh/s, dark coin at about 2 mh/s. Decided to get a used Reference xfx r9 290a enfc for 280 to the door. For mining darkcoin and an upgrade for when i play games. This 290 should unlock to a 290x witha bios flash, we'll see when i get it.
Anyways I highly recommend this card unless you can spare the extra 100 and are willing to buy used, then go big or go home :)
This review is from: XFX R9290AENFC Radeon R9 290 4GB 512-Bit GDDR5 CrossFireX Support Video Card
Pros: To my understanding most if not all of these cards come with proper hardware to be flashed with the XFX r9 290x firmware and unlock the extra shaders. I found a with a little effort that has a checker to determine if your card will work correctly or not. I just picked up a used one for 270 bucks, (was likely used to mine coins) but i trust it will work and if it doesnt unlock, oh well i have a 290 :DDD we'll see. With the increase of ASIC miners these will likely be up for sale used ( like mine) i'll update when I attempt to flash. Good luck!
Cons: i do not have it in my hands yet :/READ FULL REVIEW

Other Thoughts: WHY on earth would you skimp out on a PSU buying this card? and AMD FX9XXX series is alone 220 watts! NOT overclocked Requirement! Looking up a single 290x psu requirement is 750w, and that can vary especially if you have a 9xxx series processor even at stock. Add in the rest of the components and this card x1 and you're probably looking at your pc pulling 1100 watts from the wall while gaming if you're using said processor.
Your psu should FAR exceed the max consumption of power that your pc can use or you are likely to have BSODs games crashing/underperforming and will likely result in a psu meltdown.
Also note games do not make great use of multicore systems yet. That said AMD is severely lagging behind Intel in single core performance, therefore no matter the situation I can almost guarantee you that any AMD processor will be your bottle neck.
I have an FX8350 at 4.5ghz and an R9 270x stock, 80% of the time while playing any game my cpu is the bottleneck. GPU normally sits around 80-85% usage while cpu sits at 20%. I've seen more than one benchmark for games where an intel i3 beat out any AMD cpu based rig with like graphics cards. I'm tried and tested in this area, no more AMD cpus for me unless they pull their heads out.
TLDR- AMD cpu? + 295x? = 1200w+ psu at least. Don't like the performance/ did not notice performance increase? Get an INTEL cpu! (recommend i5 or better)
Hope this helps someone.
