What is the difference between i3 and i5 for gaming?

My business is a owner where i’d like to see to have fun with games including battlefield 3 when it comes out, gta SEVERAL and starcraft COUPLE OF.
We are also trying to find a laptop the location where the price rangers around $500-$700 with 4 gigabite of random access memory and ONE gb associated with graphics memory
Or must i get amd
THANKS

well…i5 will be newer, but that doesn’t mean it is better..as another company, Intel prices it’s products
by simply considering more sophisticated products superior…but you have an i3 running as being a i5 during any time
…what have to interest everyone for igaming is investing in a cpu with multiple main, if you want performance…it’ll run far better…and i will tell people that a number of the i5’s have as a minimum dual main, i have no idea about the actual i3’s…as well as…you shoul receive intel

you the truth is ain’t about to get significantly for 800 bucks
