But can your PSU feed it? And is your CPU fast enough? Specs, please.
It's one of the few 4850s I will recommend, for the very good reasons mentioned by Dirtmountain.
agreed with both of the above. it is one of the few 4850s that i see as well designed. (mostly with respect to the cooler). also if the rest of your system is on par with a 9400 there is a good chance the 4850 will be bottlenecked severely. great card for the price though especially if you OC it (can you say volt mod)
