can you help me to choose a graphic card which can play SC2 there.It is said that SC2 requires a high demand of computer

those are actually all good/recent graphics cards it will all just depend on what your mobo will support.for further help give your pc specs [monbo model in specific]

go with the Nvidia 8800 GT

do you always advice hw upgrades without checking their mobo specs

HE WAS ASKING WHICH VIDEO CARD ON THAT SITE WAS THE BEST.... I GAVE HIM MY ADVICE.. IT IS HIS JOB TO FIND OUT IF HIS MOBO CAN HANDLE IT... IF HE ASKS "can my mobo handle that video card" THEN I WILL GIVE HIM MY ADVICE ON THAT TOO. BUT IT IS KINDA HARD TO "CHECK THE MOBO SPECS" WITHOUT KNOWING WHAT MOTHER BOARD IT IS, ISN'T IT?

SO UNTIL THAT QUESTION IS POSED MY ANSWER REMAINS THE SAME

8800 GT!!!!!

GO FLY A KITE!

eighter your keyboard is bugged or you forgot your caps on.
no need to get excited...this is a forum not a battle field
