Right now looking at building a new system and have narrowed the choice to an Asus Z-87 A. My question is this...this model have integrated graphics, some do at least, so is it not necessary to purchase an additional graphics card now? Or is the graphics provided on some models not very good and a graphics card purchase is still a must? The processor i am looking at is the Intel Core i7-4771 Haswell 3.5GHz (3.9GHz Turbo). However there is also the Intel® Core i7-4770K Processor which is almost identical but $30 more. How to choose among the very close options. Thanks in advance for all your comments.
