I already bought the GTX280 a week after its release... and I have no regrets at all. There's just something about nVidia that I prefer, I tend to see them as being better built and more stable as a whole - I know its probably psychological, but I'm happy, and that's all that matters right? I wasn't bothered too much about the price, I had 'x' amount to spend on a new rig, so I spent it
I'm now currently playing Crysis at 1900x1200 on High, and it's oh so good...
