I have serious doubts about AMD ceasing to exist. That just wouldnt happen overnight.
If it did i guess the IT world would terribly slow their pace.
As for me, in the last few years i always have AMD machines. At the price point, whenever i buy, well, they got the "candy".
I dont like to dish 350+ for a CPU. For a GPU already did it, and ill do it again !!!!
I guess ill keep buying amd. Im mounting a Crossfire rig, so if the CPU is intel or not, ill buy AMD anyway !!!
