new msi radeon 7850 at stock OC clock speeds gets poor performance in many games such as fallout 3 where its only "playable" with over 30fps average at medium settings and at 1280 by 800. i recently upgraded from a nvidia 8800gt where it would run at 1680 by 1050 at ultra at about 40fps average. i have tried reinstalling windows incase it was a driver problem but at no avail. my system is a core 2 quad 4gb ram seagate 500gb barracuda 7200rpm drive and the msi radeon 7850
