    On a laptop which processor is better? NEW 2010 Intel® Core™ i7-720QM Quad Core Processor 1.6GHz (2.8GHz Turbo Mode, 6MB Cache) --OR-- NEW 2010 Intel® Core™ i5-430M 2.26GHz (2.53GHz Turbo Mode, 3M cache)? I'm assuming the i7 is better simply because it's higher, but I don't really know lol. Assuming it is, would it better better for me to go with the i7 and 4GB of RAM, or go with the i5 and 6GB of RAM?

    Another question. Will I be able to upgrade my RAM on a laptop?

    Any ideas? The i7/4GB RAM combo is a bit cheaper than the other, but I'm not really sure what the difference is.

    The i7 is a 4-core CPU that starts off at 1.6Ghz and Turbo's up to 2.8Ghz for a single core when all the cores are not needed, and it has 6MB of cache. The i5 is a 2-core CPU that can only turbo up to 2.53Ghz, and has half the cache. Both support HyperThreading to virtualize an additional 4 or 2 cores respectively.

    2GB of RAM difference isn't huge, and if you go with a 32 bit version of Windows 7 then you can only use 4GB's of RAM, actually its really about 3.25GB. On most laptops you can either add or replace the RAM to increase the total, unless the max is already installed - this varies from model to model.

    Also make note of other features in the laptop like the graphics cards, screen size, hard drive size and speed, weight and battery life.

    So the i7 would be a better choice for the proc.

    The laptop I'm looking at come with the 64 bit version of Windows 7. 15" screen, 500GB 7200rpm SATA HDD, ATI Mobility Radeon™ HD 5470 1GB vid card, and a 85 Whr Lithium Ion Battery (9 cell).

    I don't see anywhere what the max amount of RAM is on it, but 4GB is probably good right?

    Better, yes... but for what is your use? Basic gaming? Web surfing? Not worth the extra price I'd say. The i7 is for high end users, enthusiasts and professionals who demand the highest performance regardless of cost.

    The i5 is a better rounded processor for the average user as far as performance per dollar.

    As mentioned an i5 is good enough for the average user, the i7 is geared for high performance users. i5 is generally the better value for the dollar.

    If you post the model of the laptops you are looking at then we can tell you the max RAM.

    4GB's is enough for most people, the rest of the specs are very good as well from what you posted, a decent video card and a large hard drive.

    So is it a Dell, HP, etc?

    The standard wireless card is likely a Wireless-G card? N offers faster speeds when paired with a Wireless-N router and greater range. Centrino is a branding with the Intel chipset and processor and wireless card, I doubt that alone would raise the price $30.

    It's Dell. I believe I can choose from a G or N. The advanced Centrino one is an extra $30. Do those specs sound good for a laptop?
