Which one to buy

Choose the Intel Iris Pro Graphics 580 (integrated) if you want the faster card, and you can accept 0 GB of memory. It makes the most sense at 1440p and above, or on a monitor with a high refresh rate.

Choose the GeForce GTX 465 if the price gap matters more than the 4% speed difference, and you value the extra video memory. Whichever you pick, check reviews for the games you play, because two cards with similar scores can differ in individual titles.
