I was considering purchasing another nVidia GTX260m video card to run SLI with the current one. Is this possible and if so, how complicated to do on this computer?
It is sure, two nVidia GeForce GTX 260M graphic cards for laptops can run in SLI mode. The combination can be up to 40% faster if the game and driver support SLI properly. Some games may even run slower than a single 260M (but SLI can also be deactivated). The current consumption is twice as high as a single 260M. how complicated? you can use free nVidia tool nvidia system tools, it is an applications suite designed to help you tweak your video card. As all SLI combination, the GeForce 260M SLI may suffer from micro stuttering at frame rates between 20 to 30 fps. Because of the different frame times, an SLI combination may need higher frame rates for fluent gameplay.
Would it be more practical to upgrade to the GTX 280m instead of trying to run SLI or would you recommend the ATI 4870? I'm satisfied with the 260m for now, but I'm looking to upgrade by Christmas.
