tigerdirect has a lot of really good deals when its a holiday of some sort, but I will never buy online from anywhere other then newegg. maybe clubit if i were getting a q6600 cause they guarentee g0. but thats it.
my stories of newegg's fantabulous customer service (shortened versions):
bought a x1600 Pro, died after half a year, oc'd it too much xD, rma'd it through newegg, they were out of stock of the cards, so they gave me the original msrp from when i bought it, not what it was at the moment. (about a 50 dollar difference)
my ECS board, the cmos bracket broke so the battery wouldn't stay in so i returned it, and since it was faulty anyway they took away the restocking fee and gave me all my monies back
also they have normal people talking to you so you don't have to deal with crazy indian people. nothing against indian people (<3 verny + krazyq) its just when i have to talk to them about something computer related i want to reach through the phone and pop thier heads...
