Forget about Alienware. Nothing against Alienware here but there is no reason to pay their prices when you are able and willing to build the same machine yourself. Between a desktop and laptop - how much horsepower do you want? You can obviously pack more into a tower. That's the way I would go if I where you, unless you need to be mobile - in which case, get a laptop. Hope that helps your decision process...
I'd like to be mobile, since I record and upload content to Youtube (my internet at home is terrible, unable to upload videos without it being several hours(5-6 hours for 15 minutes)). My CPU is not made to stream, something I used to be unaware of at the time. And I've always enjoyed mobility, since I go to my Grandma's many frequent times during the weekends. The Laptop I'm looking at has the following:
CPU: Intel Core i7 6700-HQ (2.6 GHZ)
RAM: 8GB DDR4 RAM
GPU: NVIDIA GTX 960M GPU (2GB, 1092-1202 MHz)
Hard Drive: 1 TB HDD 5400RPM (Probably will change this to an SSHD)
Resolution: 1920x1080
Vs my Laptop
AMD A8-5545M APU with Radeon HD 8510G Graphics (1.7 GHz)
8GB DDR3
1TB SSHD (custom built in)
Resolution: 1366x768
My potential PC build stats are unknown, but I know that the other Laptop is better than the one I have. But I'm worried that it might not be worth it to upgrade, even though I'm sure it is (there's also things between my mom and I). I'm sure I can sell my Laptop for around $600 (that's around what we bought it for, and I can get the other Laptop for $892 at Best Buy in Open-Box).
So basically I'm looking for a machine where I can record/stream Youtube videos (maybe with Webcam, impossible to do on current machine, I get very low frames below 30), and record PC footage (again, low frames below 30). I'm also looking to play Black Ops 1 and maybe 2 & 3, Minecraft, Garry's Mod, and CSGO.
