I am planning on having it built with a ATI HD 5770 Video card. My main concern is that the system has merely a 300-watt power supply. AMD RECOMMENDS a 400-watt system for this card. I plan on doing marathon gaming daily (Final Fantasy Online- http://www.ffxivinfo.com/systemreqs.php for requirements).
Will a 300-watt system suffice with this setup; do you think this system will be sufficient?
PS. I cannot even buy the components and build a system like this for the asking price (639)
