I need something that can run Dragon Age 2 and Flight Simulator. As you can see the Integrated card just wont hold up. So with a budget maxing out around $200 what should I look at?Some suggestions on a graphics card.?
uhm flight simulators are very gpu intensive but id say get a quality 550-600 antec psu and that will cost round 60 bucks ,and that will leave you like 140 so a radeon 6790 would be the best choice itll cost round 137 for the his version which is a great card, this is on newegg and comes with dirt 3 for free, but idf you can afford an extra 20 you can get a radeon 6850 from saphire which is by far the better performer and it comes with dirt 3as wellSome suggestions on a graphics card.?
A new power supply is a must. You can get a decent 550w for about $50. DO NOT cheap out. You should have enough left over for a Radeon 6850.
