first,sorry if my english bad :p
i want to buy a new graphic card :
1.GIGABYTE NVidia GeForce GTX 650 [GV-N650OC-2GI]
or
2.ASUS NVidia GeForce GTX 650 Ti [GTX650TI-1GD5]

i've been thinking about it over a week and still dont have an answer

i want to be able to play a middle to high-end game,and to have dual to four monitor (if i have more money)
3 monitor for gaming,1 for watching and other things
here's my computer specs http://valid.canardpc.com/9068ka

EDIT: the monitor is 1920x1080P
(ASUS question)
1.can i run 4 monitor at once without having a lag? (ASUS say this card can run 4 monitor at once,but because the memory is only 1GB,i dont think it can run smoothly)
2,can these card run 3 monitor at once for gaming (like NFS Hot Pursuit)

(GIGABYTE question)
1.can i run 4 monitor at once without having a lag?
2.same question

so which one is Better ?
if you have a better graphic card with budget around it,please tell me :D,thx
sorry if i asking to much! :D
