Here’s a list of games and expected frame rates at various settings: http://www.notebookcheck.net/AMD-Radeon-HD-6630M.43963.0.html

Core i3:
* Entry level processor.
* 2-4 Cores
* 4 Threads
* Hyper-Threading (efficient use of processor resources)
* 3-4 MB Catche
* 32 nm Silicon (less heat and energy)

Core i5:
* Mid range processor.
* 2-4 Cores
* 4 Threads
* Turbo Mode (turn off core if not used)
* Hyper-Threading (efficient use of processor resources)
* 3-8 MB Catche
* 32-45 nm Silicon (less heat and energy)

Core i7:
* High end processor.
* 4 Cores
* 8 Threads
* Turbo Mode (turn off core if not used)
* Hyper-Threading (efficient use of processor resources)
* 4-8 MB Catche
* 32-45 nm Silicon (less heat and energy)

With mobile Core i3 and Core i5 processors, both are dual core with hyperthreading…. 2 cores, 4 threads. Core i3 processors run at the speed they are rated at. Core i5 processors can and will “overclock” themselves when you need extra processing power.
These are all the first and second generation Core i5 mobile processors… http://ark.intel.com/ProductCollection.aspx?familyId=43483

Check any of them out… you’ll see what I mean.

Is the difference enough for you to pick a Core i5 laptop over a Core i3? How should I know? You have said nothing about what you intend to do with the laptop. You haven’t said what games (if any) you intend to play on it, etc, etc. Is it better to just buy the best and fastest laptop possible? I don’t think so. But that’s up to you.
