> AMD if you like gaming.
That used to be true.
The Core 2 Duo chips outperform all similarly priced Athlon 64 and Opteron CPU's when it comes to gaming, and to just about everything else.
Any incompatibility (issues) you saw in the past were probably more due to a cheaply made and poorly engineered motherboard rather than the AMD processor, a company looking to scrimp on costs will scrimp on everything.
There are not many, if any, games that use a dual core processor right now. I used to be an Intel user, but that all changed after I tried an AMD. I only care about performance, so I am not an Intel or AMD devotee as many people are.
