Hey everybody. I'm planning on buying an iMac this week, but I first need to sell my (relatively new) PC's. I don't know whether or not to get the 2.4ghz one, or the 2.66ghz one. I want this computer to last me for the next four years, as I have been buying and selling computers so much recently its rediculess. I mainly just to simple things like web browsing, iTunes, ext., but I also do some video work and encoding. I also plan on doing some light gaming, like with Spore when it comes out. If price was not a factor, I would get the 2.66ghz one, but money is a little tight since I'm not able to sell my PC's for as much as I thought I would be. Overall, is the extra processor speed and video card upgrade a big deal, as for what I plan on doing, and longevity wise? Thanks!
