urgent graphics card upgrade question

[csol]

Hi, I want to move to 3 monitor, could I get some advise which graphics card I can add to my existing spec:

mboard: ASUS® X79 DELUXE:
graphics card existing: 1GB NVIDIA GEFORCE 210 - DVI, HDMI, VGA
case: CORSAIR CARBIDE SERIES™ 300R COMPACT GAMING CASE
psu: CORSAIR 650W RM SERIES™ MODULAR 80 PLUS® GOLD, ULTRA QUIET

no other PCI slots are used.

Can I add another GEFORCE 210 or a better GEFORCE GT720 for example ?

Thanks for all your help everyone !

You can add virtually any GPU you want, but I wouldn't bother adding a 2nd gt210.

it does depend a bit on what you intend to do with 3 monitors, just work, gaming etc? if its gaming you will need something much better than you would if it were just for office type applications..

Also what is your budget for the upgrade along with the other components installed in your system?
