hey everyone, i just need to verify somethin. i just bought a toshiba laptop a205-s7464 and it has an intel core 2 duo processor t5250 1.5 ghz, 2 gig of ram, and mobile intel 965 express chipset family for my graphics card. i just barely bought 3 games with it. Fear, doom 3, and half life 2: episode 2. i can only play doom 3 as of right now. The others i have trouble with because of my graphics card, but i also think its because of my ghz. is it possible for me to upgrade my graphics card and my ghz?
