are you looking for a laptop?
i'd honestly look at an ultrabook laptop with a new i7 Haswell processor...those have really good integrated graphics and if you get one with good RAM and an SSD...it would be really slick.
i have always used Dell computers and always had good luck with them, but only because i figure out problems on my own instead of using their customer service.
i was looking at cyberpowerpc today and they have nice computers for decent prices, but there are really mixed reviews...either terrible or great customer service and products.
