I should be getting my new pc bits tomorrow, I5 3570, Gigabyte Z77 DSH and 16gb of Corsair ram 
My current Pc has 2 video cards in it so that I can use 3 monitors.
1 monitor connected to my Nvidia 460GTX for games, and 2 other monitors on an old ATI 3650 for my work.
Just wondering with my new i5 3570 can I sell off the ATI 3650 and just use the IGP for the 2 'work' screens and plug my main screen to the NVidia 460?
Is it better to keep and use the ati 3650 or use the IGP?
Thanks.
