MrFoxRox :
That is actually not correct in all cases. You have to know your machines and their limitations. Laptops that have BGA CPU and GPU are disposable trash that are not upgrade-friendly. Laptops in general are often garbage, but there are some that stand out and are truly superior products. The MXM modules in some machines can be proprietary (think ASUS and MSI laptops), but others are generic. Alienware and Clevo are very upgrade-friendly. The upgrades are super easy on Alienware and Clevo laptops with CPU sockets and MXM slots.
I have made many CPU and GPU upgrades to my Alienware systems, and in multiple cases used Clevo MXM cards. Clevos can also use Dell/Alienware MXM cards. I have gone from 6970M CF > 6990M CF > GTX 580M SLI > 7970M CF > GTX 680M SLI > GTX 780M SLI in a single machine. It takes about an hour from start to finish, and it is MUCH less expensive than a new laptop. On a machine that costs upwards of $4,000 spending $1500 on 980M SLI is not a big deal, and the finished product will destroy the vast majority of "gamer" desktops.
You will see a MASSIVE increase in performance over 880M SLI. Running at stock clocks the 980M SLI will match what your 880M SLI can just barely do with its max stable overclock. Stock versus stock you will be absolutely amazed of the performance increase.
I know this is an old thread, but I don't want to see an adventurous person with competent technical skills scared off by people that don't have the right answer for an Alienware or Clevo owner.
Hi MrFoxRox, I have a late 2013 Alienware 780m SLI 4gb.
I have my cards overclocked & also my i7 4930mx overclocked from 3ghz to 4ghz, this makes a huge difference & I can run GTAV with some ultra settings in 2k smoothly for example.
I actually think my Laptop runs better than my PC rig which has a 780-TI UC.
I am, however interested in upgrading the 18 setup to 980m SLI.
How does the driver & bios situation work out though? A few scary messages on here putting me off?
Also, how can I get my hands on the GPU's?
Thanx in advance!
