Quad core of coarse, even if they did not use it all now, What do you want to buy a new PC next month or next year. You want a couple years out of it, buy the best you can for gaming , the stronger CPu the better, then you can upgrade the graphics card , and get another year or 2 out of your machine before buying a whole new one. PCs change over night, buy the absolute best you can NOW. Good Luck.
