The "dual core is dead" lobby needs to realize that maybe only 5% of the population is into graphically demanding gaming on the PC. (Just my personal guess, but I would bet pretty accurate.) In any case, a dual core is more than adequate for the vast majority of users. Heck, the market is even moving down to "quad core" celeron, pentiums, and cat cores, Axxx, whatever they are. (Not sure which is worse Intel's or AMD's naming system to try to slip small cores into the big core lineup.)
I find this more disturbing than people still running dual cores.
I also dont understand the sentiment of those who want to raise the bar artificially for minimum requirements for PC gaming. Why? What does it hurt someone if they have a quad core while someone else can still game adequately on a dual core. Personally, I have a quad i5, but I am adamantly against artificially locking out dual cores or making the game not run on them by lazy programming. I enjoy PC gaming and I would like for as many people as possible to be able to participate in the same hobby.
@crashtech: you are correct that an i3 is a dual core, but I think the "anti dual core" crowd really means a non-hyperthreaded dual core, although they are using the term improperly.
