I want to buy this laptop from Littlewoods.Is it upgradable?The laptop is a Toshiba At 499 pounds.
Not enough information. If you haven't yet made the purchase, it might be better for you to decide what you want the laptop to do and buy accordingly, rather than buy and upgrade. If you have particular software in mind, I would go to Toshiba help and support, get the specs of the laptop, then get the requirements of the software you would like. See if the laptop will be able to run everything you want.
shared graphic cards are mostly found in most of te mid range cards that are out nowadays ati calls it hyper memory and nvidia calls it turbo cace even tough they both are basically the sme thing there are samll differences and make the consumer tink that it is thae actual memory available when actually memory is taken from the ram or random access memory there is a way to inrease performance but not drastically by increasing the ram therefore increasing syastem performance nand being able to dedicate a fair amount of ram memory to the graphic card graphic cards usually sold as 256mb shared have 128mb shared and the the rest is shared from the ram so therefore the lesser is the ram the worser cards sold as 512 shared have 256 dedicated and 256 taken from the ram or 128 taken from the ram so therefore a gud amount of ram is required to increase performance and so that the card will be able to perform to its full potential u can also increase the performance of the card by increasing graphic acceleration bar at thegraphics section in control panel menu
