Say no to intel.
For today's generation, 6770 and below, go and get AMD/ATi
When you go better than 6770, go get anything you want, because it is based on personal preference only.
My next one is going to be AMD/ATi, after nvidia, after AMD/Ati, etc, etc, etc... Just changing and changing, my current one is nvidia.
But I voted for AMD/ATi, because they are winning in today's generation in my opinion.
