Hey guys. I kinda new to this forum and i don't know anything about graphic cards. I want to replace my graphic card because i think it is the reason why all the new games are runing slow. My current graphic card is ATI Mobility Radeon HD 5470 which as i think its one of the oldest. But my laptop is vaio VPCEC4S0E which have I5 processor, 6GB rams(the most basic stuff). I'm planing to buy the newest version of graphic card that can fit inside my laptop. I'm not sure that it is a good idea to open it as i'm not experinced enough. So can someone suggest me the best graphic card that i can have? Is it a good idea to upgrade my graphic card to ATI Radeon HD 5970?? Will that fit into my laptop? Is it a good idea as well to install 8GB rams? (my maxmimum input of rams is 8Gb).
Guys i really really need your asnwers. Help me.
