    I am about to place my order for the HP ENVY 15 and was wondering do I really need an i7 for what I will be doing? Think I plan on doing, is watching tons of movies, shows streaming and listening to music, running Office Suite and I will be using Fruity Loops and the only game I will be playing is Diablo 3 when it comes out..So do you think i need an i7? Whats the main difference between those two?

    Difference is # of cores. A few other subtle differences which you wouldn't engage. You'll be plenty happy with the i5 as it is more than enough power for what you do.

    Consider also, that Core2Duo CPUs from a few years ago have no issues running the apps you use. And the GPU is very good also.

    I will offer the other side of this, you can never upgrade your CPU, and so for the small price to bump up to an i7 you get 2 extra cores and a bit more speed. Maybe you don't think you need it today, but it might be something you like later.

    For example, maybe you want to play Diablo 3, listen to music, have a Skype call, all while using your web browser. A quad core is going to perform noticeably better in a situation where you multitask than the 2 core i5.

    Nah bro, you can definitely upgrade your CPU. Many on this site, including myself have upgraded their CPU on various models. Though, in come cases, upgrading the CPU means having to get a new mobo. Now, the GPU is another story since the majority of GPUs are soldered to the mobo. Just responding to the "never" part. But point taken in that some may not be adept enough to do the job.

    Also, one can multitask just fine with an i5. While it has two physical cores, it has 4 logical cores (threads). OTOH, one of the benefits of a quad core is 4 physical cores and 8 logical. If one uses multi-threaded software that can capitalize on the extra cores , like some rendering, encoding/decoding software, or Photoshop, then by all means get a quad core. Otherwise, it's overkill that will be under utilized.

    But if one is not doing any of this stuff now and plans to buy a new system in a few years, no real point in spending the extra coin to "future proof" their system with a quad-core.

    thanks for the input i might just buy with i7, since i plan on keeping the envy for a few years.

    I had no idea it was ever possible to upgrade a laptop CPU. When I checked into it in the past both the GPU and CPU were generally non-upgradable without serious equipment.

    How much into the "future" are we talking about here? Im having doubts as well since id much rather save $100 if i realistically wouldnt need an i7. What kind of tasks will i need to be doing for there to be drastic differences whether i have an i5 or i7?

    No worries, mate. All that one needs is a screw driver (philips) and a razor/straight edge to spread thermal compound.

    Heavy duty computing. Gaming? No, since the majority of games are not deigned to use a quad core. But a i5 is a type of quad core in that while it has 2 cores, each core has 2 threads of logical cores. The dual cores before these were 1 thread per core.

    As for the future, windows 8 isn't going to change that since it is being designed to run very well on older hardware like the Santa Rosa chipset.

    The overwhelming majority of users have no need of an i7. You need to be running multithreaded apps and/or do a great deal of multitasking to even begin to notice a difference. I have notebooks with Santa Rosa, Montevina, And Sandy Bridge chipsets. For my normal course of activities, I can't tell a single difference between them. Only difference is gaming. But that is because of the different GPUs.

    Im definitely gaming, but i guess sknce you say it wont make much of a difference im more worried about the fan noise and heating differences between i5 and i7.

    Which would tend to heat up more? an i5 or an i7?
