Who do you think is best? Post away :)
Just get the best price between amazon and newegg. Ocassionally if you want something a bit more rare you may have to look at NCIX.
Depends on where you live. Newegg and amazon is good for America. But i live in Norway so i use Komplett.no :3
pcpartpicker.com looks at amazon, newegg, ncix, and a few others....
