<p>I think the difference between 2.6 and 2.2 is not big but if you are a heavy user, you’ll notice the difference. RAM plays a big factor too. For a laptop, you should have at least 2GB of RAM. If you want to splurge and get 4GB, you can. Just make sure you get the 64-bit version of Windows or whatever operating system you are using so the computer knows to utilize the full 4GB of RAM.</p>
<p>For a graphics card, you want a dedicated one. Don’t get the shared ones.</p>
