Скажите плиз Battlefield Bad Company 2 на такую конфигурацию нормально потянет?

да не просто потянет а полетит )))

А сам как думаешь, на моей конфигурации пойдет?

А вообще, нечего завадать таких вопросов.
Производительность зависит далеко не только от видеокарты, ЦПУ И ОЗУ.

Пробуй - заходи - проверяй. Будет тормозить - вырубай всё лишнее, занимайся дзеном, оптимизацией и обновлением железа (в частности, оперативной памяти еще 512/1024 МиБ неплохо бы).

запустить запустишь
играть тоже наверно сможешь но не на максимальных это точно
