Ebay
btw, dont get sucked into the idea of dedicated graphics. While yes, its good, it doesnt mean that a laptop with dedicated graphics is an uber games machine. The graphics card in that laptop is a fairly low end graphics card. It WILL play new games, like Crysis on low detail and mediocre resolution. So its not that bad. (but with the AMD im not sure it would do quite as well)
Im guessing that this is what you are looking far anyway given the price range. Remember when buying a laptop for gaming GPU >> CPU. But still, dont get a celeron
Compare laptop graphics cards
Im pretty sure an i3 is dual core with hyperthreading, so 4 threads. i5 will be quad core (still 4 threads) and i7 is quad core with hyperthreading so its got 8 threads. Or something like that, its not quite that simple. In general i3 < i5 < i7. Basically more threads = multitasking.
That AMD is dual core < i3
Compare laptop processors
Follow the links around, they have tested games with most graphics cards. You can check what type of laptop/processor they were using with the graphics card when they tested it. Its pretty simple and neatly set out which makes it useful.
For example at the bottom they have test results for many games.
They have benchmark lists and comparison lists for both processor and graphics card, so you can directly compare graphics cards and processors (within not between duh
) (to an extent)
There should be plenty of laptops around that price range, just cross compare their graphics cards and processors and see what works best. Id try go for i3 though (but i dunno what thats gonna do to price, im not gonna do browsing right now
)
oh and i did say ebay, but you dont necessarily get cheapest there. I got a AU$2100 (RRP) laptop for effectively AU$1310 from JB HiFi
[edit] btw, thats pretty cheap, so its gonna be hard to get something if you want half decent gaming and general 'quickness'.
If you dont want gaming, ie you want to do word docs/listen to music/internet/other work/education related programs, then go for the i3 and ditch the graphics card
