Can anyone recommend a card for a monitor in these sizes. Monitor is most likely going to be 23 or 24" for the office at work. Computer isn't used for games or anything like that but rather for business apps, watching videos, etc. Their's so much out their it's confusing with all these model numbers and such. Don't know the differences between a 128 or 256 bit card or if a 1gb or 512mb card is needed. Just one monitor is going to be used.
