Unlike Desktop graphics cards, which are limited only by available slots, Laptop graphics cards are hard to find, and even harder to replace.



Laptop GPUs are not cards at all, but GPU chips soldered into the motherboard (which is why the ones with dedicated cards are said to have "discrete graphics" and others have the built-in "integrated graphics" rather than having "cards"), so as are some of the CPUs - meaning you have to melt the metal solder to even take them out. This is the way most laptops today are made. You'll have to be a real expert to be able to swap them successfully - even then success isn't 100%. Manufacturers will not take them back for an upgrade. Furthermore, your laptop motherboard chipset will not allow for you to upgrade to a discrete GPU if you ordered it with the integrated card.



Unless you have a laptop with a separate graphics unit or an MXM slot, you won't be able to upgrade/replace it. Check your manual to see if they allow any upgrades. Few laptops today allow you to do so (the Alienware line being one of the very last)

The only option you have left is to use an Expresscard-adpated graphics unit, but not yet. Maybe in the near future; right now external graphics through Expresscard is in the process of development/release.



There aren't that many for sale yet, but if you're lucky, you can find an ASUS XG Station for sale somewhere (but it won't be cheap considering its around $300 for the dock alone). You just need to have an Expresscard slot.|||Laptops can be rarely upgraded.

Ask your computer vendor if your laptop supports upgrade.

If yes, then go for the best graphic card that fits your budget

The newest are Nvidia Geforce 9 series. they are way too costly. They are made for better gaming experience than play station 3.

Otherwise go for geforce 7300 GT 512mb. Dont put in ATI or AMD graphic cards NVIDIA is best.|||i dont know much about computers but my friend said he would do it for me for just the cost of the new video card?
