The latest ones crash ALOT if you read maximumpc.com or tomshardware.com and my Nvidia fanboys I raid with.
AMD has better quality hardware with less flaky voltage regulators. I went through 2 nvidia cards over 8 years that failed and switched all AMD/ATI in 2010 with the phenom II (better that steamroller per clock tick sadly ) and an ATI 5750.
Had one bizaare issue with black edges on the screen when switching to HDMI. That problem went away after I went into the drivers and configured my screen to not do underscanning.
NO issues for 2 years! Just upgraded to an ATI 7850 and it runs GREAT. No black screens, no overheating, no wierd driver issues at all. This was true in 2002 with the ill fated ATI Rage Pro 128 TV adapter. The Mac version was the only one that worked ok.
But damn that was 11 years ago!
I admit I do not like steamroller, but over all I got a nice $600 system that is 6core, runs VMWare accelerated, back in 2010 back when I would need an Intel extreme edition for $700 without anything else but the damn chip!
What they do not tell you is Intel cripples the bios and turns off hyperthreading and Virtualization support to force you into the more expensive units. AMD chipsets never do this.
IF AMD gets their act together and not create underperforming space heaters I will consider AMD again for a CPU purchase. But what I have works great and the phenom II was a pretty competitive chip for its time.
Raedons are great GPUs and are very competitive with Nvidia. Drivers are worse today with Nvidia unless they clean things up.
