    Thank you Dantee. I tried configuring the Clevo with 1070gtx and the price goes up to almost 3k with windows installed. Crazy difference

    If indeed its the laptop that Pete has fixed, and it comes without issues then I can see a better bargain. The 32gb ram is a bit of overkill but anyway

    Can the 6820HK cpu be upgraded if I want to, to Coffee Lake or the motherboard won't support it?

    You will have to buy a whole new motherboard for a CPU upgrade

    He's getting 32GB Ram with a 1080 much better value bot to mention the 512GB SSD... I would advise the clevo as you can always upgrade it later on down the road, get a new GPU or CPU. But it will be better bang for buck to go for the Alienware. But you won't really be able to upgrade that.

    Thank you. I had pc specialists in mind. It goes around 2200 GBP with 16gb ram and 500 ssd 960 Samsung, but it is lacking the 1440p screen and the 1080gtx, but u get the the 8700 cpu. 300 pounds for just a better cpu worth it, while you lose the 1440p screen and 1080gtx?

    No but you will be able to upgrade the GPU and CPU later if you want... Personally I would go clevo route but u said u don't want to upgrade for 4 years so I don't think it's a big deal for u

    Thank you for your post again. I think the reasonable purchase at this moment, taking into consideration the price factor and what you get is to go with alienware. Unfortunately, the systems that you get is like the lotto so it might end up being a pain in the ass. If I buy the 7820hk one, I think the gap has closed and it should be a straightforward purchase. The only thing I am afraid is the heating problems.

    I am telling them to book it for me and I will see.

    Spoke with pc-specialists, they can't do any better prices unless there is a competitive quote from Dell for an identical system.

    I didn't say I disagree with you. The GPU is more important for sure, but that statement from you that there's not much difference is not correct. You will not be able to overclock the 7700HQ to make up any difference. In fact, the opposite is true. That 9% difference is the maximum the 7700HQ can run at but not the maximum the 7820 can run at. I overclock my 7820 on a daily basis to 4.3GHz (and it can go more!). that's nearly 35% faster (especially taking into consideration the additional 2MB cache). Like I said, big difference...

    Regarding the CPU affecting game performance an important clarification here is that age isn't necessarily a factor anymore. Early gen i7s are fine because the clock speed is still high, in this example the clock speed of a 2700k is still comparable to a 7700 in terms of speed so not much difference. what got better since then is mostly power consumption additional features and HW support and form factor (allowing higher speeds in smaller laptops for example).

    However, for reasons stated above, I still notice at least a 20 FPS drop in BF1 if I run at 7700 speed instead of 4.3GHz because I have a 1080 and the CPU just simply isn't able to keep up with the demand. I'd say that was noticeable enough that people should be informed...
