I will be purchasing a laptop soon (low budget) to use for gaming and other general things (word processing, web browsing, etc). Whatever laptop I choose will have a discrete/dedicated graphics card, so that part of the equation is removed. I can either get one with an AMD A6-3410mx quad core, or for $100 more I can get one with an Intel i5-2430M dual core. So, for gaming which is better, the AMD's additional cores or the Intel's higher clock speed?
