It is a good card for it's price, and depending on games, the HD5850 is sufficient for HD gaming,
@op what games do u play?
street fighter 4, borderlands, left 4 dead 2, dragon age 2, the witcher 2.
of coz, i don't want it to be performing well only in older and current games (which rises the need to upgrade in short-time frame) but also upcoming games like dungeon siege 3, diablo 3 and other games in the next 2-3 years. naturally, i don't expect to play games at ultra high settings by then.
btw, how about its overclockability?
