Hi, i am new to building computers and i was looking to upgrade to a decent gaming pc, mainly so that i can play battlefield 4 and other games. like most people i want to do this for as cheap as possible, but at the same time if that means that i will end up with a rubbish system that cant handle games then whats the point! i am not overly fussed about ultra setting (alothugh it would be nice) but high settings with 60 fps would be good. so far i have this; http://uk.pcpartpicker.com/p/1XPbz
basically i want to know if i am way of the mark?
are there any parts in this build that are over powered or under powered?
what size case would fit this all in and do i need a fan or would the one included be powerful enough?
and any other bits of advice would be great, sorry for all the questions very new to all of this :
i have a dell xps laptop so sadly i think upgrading is very difficult if not impossible. if i had this case http://uk.pcpartpicker.com/part/cooler-master-case-rc91... would it be large enough? and the fan decent enough to cool the system? thanks for the answer nice to know i am on the right track!
