hi i have a Toshiba Satellite X205-S9349 Notebook and im trying to upgrade the cpu wich cpus i can upgrade to,a program called pc wizard tells me it has socket p (478) which cpus will my bios support and if not can i upgrade the bios so it does

First let's find out what you're trying to accomplish. Why do you feel the need to upgrade the cpu?

Looking at the specs, it's a pretty well configured machine. http://www.newegg.com/Product/Produ... And socket P is not the same as socket 478. Why do you want to upgrade the CPU? I just checked newegg & they only carry one socket P 800MHz FSB CPU...the T7500 which runs at 2.2GHz & cost $250. That's a lot of cash for a 400MHz upgrade in clock speed. http://www.newegg.com/Product/Produ... http://www.anandtech.com/printartic...

well i dont want to buy another laptop, and i played some games like empire total war and its slow cant handle them with the highest configuration, so i wanted to upgrade for better results in games, and what sockets does the mother board supports, also i wanna upgrade the ram, i know vista only sees up to 3 gigs is it still worth it to upgrade to 4

"and i played some games like empire total war and its slow cant handle them with the highest configuration, so i wanted to upgrade for better results in games" Likely more of a video card/chipset issue than a CPU issue. "also i wanna upgrade the ram, i know vista only sees up to 3 gigs is it still worth it to upgrade to 4" You'd really need to upgrade to a 64-bit version of Windows to see the "full" 4GB of RAM... http://support.microsoft.com/kb/929605

then can i upgrade the video card i've read u can with a 8800m gt
