Hi sorry if you guys are tired of this lol core i5-450m 4 gb ddr3 ram nvidia geforce 310m with 1gb vram my graphics card is what worries me, i have basically zero computer knowledge and my tech friends tell me that the 310m is one of the bottom line video cards and won't be able to run starcraft 2 at all. AND they said i can't change the graphics card because on laptops they are built in or somtehing and you can't manually change it. will i be able to run this on medium settings across the board? I don't plan on playing higher settings than that. is it possible to upgrade to a better graphics card if i can't?? thank you.
