I got the i5 version of this (without the 4K screen) for Xmas. Within 3 weeks the charger went pop and then I found the USB3 port plastic had disintegrated. In Lenovo's defence the pins in the port look very sturdy but that means the plastic is very thin. It seems they had similar problems with broken USB ports in the USA and replaced motherboards without a fuss. The laptop also got very hot in use with the graphics card configured in, the bottom of the case was almost unbearably hot I was concerned the chips would desolder themselves off the board.
Sent it back to the supplier who refunded me. Now bought the Dell 7559 with i7 processor and 4gb 960m graphics. It's chunkier but feels sturdier and remains cool to touch in use.
The Lenovo looked nicer but I think the Dell will last longer.

4k screen is a little pointless considering the graphics card in question. 2GB GDDR5 is also going to severely limit what current games you can play. Not sure what the manufacturer was thinking with that imbalance. A lower res screen making way for a slightly beefier GPU (965m) would have been more preferable and better balanced.

Good option for multimedia work and last gen games, though.

A 960M is.... not the strongest card. It's not BAD but... it's certainly not going to knock anything modern out of the park.

Here's the competition (Inspiron 15 7559) in review at notebookcheck (similar card, this ones the 4GB version though):

have had this for the last 7 months.
Street fighter 5 plays on the lowest settings -(for those interested) pre 2015 games play med - to ultra settings

I've ordered. Light gaming with some video and photo editing seems ideal.

Windows 10 isn't the issue. You can set the resolution to 3840 × 2160 and it works fine. It's the programs. I find alot of my programs the text is really small when my resolution is maxed out. That's why I just leave my resolution at 1080 like most other users.

Have the scaling issues been sorted with Windows 10. How much of an issue is it. From older reviews just reset to 1080p and reboot. Is this still the case.

Silly PC gaming snobbery. Some laptops simply cannot play games worth a damn. Some can play games moderately well.

It doesn't matter if some other thing would be better in circumstances that don't apply: if you NEED a laptop, the distinction is really valuable.

I've had this laptop for over a year now. I'd advise upgrading it to Windows 10 asap, as it runs flawlessly on this system and works better in a non touch screen environment. The 4K screen also creates some nightmare scaling issues with quite a few programs, even some issues with Windows 10's menus too, but it is beautiful and crystal clear. If you're considering it as a gaming laptop, be aware that the screen refresh rate is locked at 48Hz, due to the limitations of the screen. This problem didn't exist on the Full HD Panel, but that display was fairly poor. Some games will suffer and stutter and you'll have real issues with games that demand 60Hz+ refresh rates, games like BitTrip Runner being a prime example. Run it through HDMI to an external screen and it's fine, obviously, but defeats the point of having a laptop! I've been playing Fallout 4 at 720p at High settings on my 42inch Panny Plasma and it runs silky smooth and flawlessly, which surprised me. I'm surprised about the tiny drive, as mine shipped with a 1TB hybrid. It's not a bad machine, but build quality wise it doesn't match my previous Dell XPS laptops, but for £700, wouldn't be a bad decision. It's quite slim and svelte, probably about as portable as any 15 inch laptop can be.

Rather an ask loads of questions about each part of the laptop setup, are there any articles out there you're aware of which break down what's the most important specs to have for a gaming laptop these days?

What would be considered a balanced system? I'm guessing 4k with only 2Gb graphics is unbalanced?

Thanks in advance and apologies for the beginners' questions.

brilliant specs on this

Stupid unbalanced specs, they just crammed that 4k screen in as a selling point.

Not sure if the screen is TN or IPS?
2 generations older CPU than some of the dell offers - more heat I guess.
£91 warranty extension looks a sensible idea - but pushes the price upto XPS 15 range.

great price ,used to own one, crappy screen though

Can this play street fighter v @ 60fps?

How much better is the 965m over 960m?

Great price, heat added

Good price.
Just a suggestion; might be worth putting gaming laptop in the title?

Sorry, I've just deleted my post - went to get the link, then realised it was no longer listed. Can only assume they have sold out. Got mine on Wednesday. Worth keeping an eye on their site though

You got a link I can't find it on the site

Looks good, dedicated graphics and 4k screen.
