The thing I discovered about laptops is, they're a lot more finicky than workstations. But if the laptop manufacturer recommends or offers different video cards, then they've likely tested those cards with their laptops. But I would call them and 'grill them' to be sure, b/c sometimes they don't do adequate testing and have issues. I found the DRIVERS to be the biggest issue on laptops. Usually one driver conflicts w/another driver. But that's what the laptop mfgr is supposed to sort out for you. One thing about the HP Zbook I had is, HP DRIVERS SUCK. They're always updating them, and if you're not careful, you can royally screw up your system when applying an updated driver. So that's why I would caution you to do your homework before spec'ing anything on a laptop.
Here's an anecdotal story for you:
A number of years ago I bought a "Digital Storm" workstation on a recommendation by someone I thought I could trust. Turns out that after a lengthy conversation w/the builder, they screwed me with their choice of RAM, which I didn't discover until a year or so later. You see, I wanted to shave a few hundred bux off the price, so they did, but they used incompatible RAM to do it. Eventually I had MAJOR stability problems w/that system. But that's only the beginning of the story.
The thing about building systems is, their tech genius (engineer) may be a wizard 'builder', but the average Joe doesn't know 1/10 of what those guys know. So when I ran into problems w/the machine, I couldn't figure it out. And I'm not some yahoo idiot. I've build all but a few of my workstations over the years starting w/286's, and never had any problems figuring out how to make things work together. But this thing was a NIGHTMARE. Anyways, when I finally got compatible RAM for the system, it appeared to run stable ... FINALLY! I thank ADATA for accommodating me.
But after a week of running, a whole different set of problems began occurring. Finally I said "f**k it" and got another motherboard b/c I had enough of struggling w/this thing. Note: The m/b I got was an EVGA factory replacement for the one that the original builder installed. Actually it was an upgrade b/c they no longer mfgr'd any of those m/b's that I had. But b/c it was on the tail end of an extended warranty, they sent me a 'Refurbished' m/b. It was EVGA's top-of-the-line too. EVGA decided to treat me right b/c of 2 things: 1. nobody could figure out what was wrong w/my machine (neither Digital Storm nor EVGA), and 2. they wanted a happy customer. They made me happy, well ... at first.
But before I installed that 'Refurbished' m/b, EVGA QC'd the board I returned and contacted me w/the results (claiming it was my fault). Turns out that some of the CPU socket pins were BENT! But b/c I didn't build that system, it couldn't have been MY fault. So the facts underlying ALL the problems I had SINCE DAY-1 all pointed to EITHER 1. the Digital Storm assembler BENDING THE PINS when installing the CPU, or 2. EVGA did it somewhere along the line and it never got flagged by their QC guys.
However, I think it was EVGA's fault, b/c the first thing I did after receiving that news was break out my 40 power stereo microscope and QC the CPU socket for bent pins. What do you know! I found at least 3 BENT pins. After taking some pics of those 3, I quit the QC operation. Anyways, long story short, EVGA sent me a NEW m/b and it worked flawlessly until I decided to upgrade to a faster system. But I still doubt that the original RAM would've run on that new EVGA m/b, b/c it was not on EVGA's compatibility list. And even though the engineer at the Digital Storm COULD get the incompatible RAM running stable on the first BENT PIN system, that doesn't mean I or YOU could do it (b/c I couldn't!).
So my advice to anybody picking components for any system is ONLY USE COMPONENTS ON THE 'COMPATIBILITY LIST', unless you're an expert system builder who can 'fix anything', or unless you want to throw good money after a big risk when buying non-certified or untested 'bleeding edge' components (which I've also done a number of times in the past). The latter would be considered R&D.
Considering those problems occurred on a workstation, I think it's even more important to MAKE SURE you use manufacturer-certified components on LAPTOPS, b/c they're so finicky compared to workstations (esp. m/b's designed for overclocking, which are pretty easy to build).
Again, just my 2 cents' worth ...
