absolutely. they stand behind their products 100%. they maybe a bit more expensive than other manufacturers but their products r solid and very stable even under extreme conditions. which is y i always buy a XFX nVidia card. i've never had a problem.
from what i know and from what i've seen..the 480 has a pretty nifty cooling system. nVidia has gone on record to state the 4xx series will consume a lot of power and will heat quite a bit but that will not affect its functionality nor its longevity. this series is designed to work under a lot of stress.
Being a gamer requires a gold mine!
yea i know how u feel. a really good psu is at the very heart of a good gaming rig. Thermaltake, Lian Li, Cooler Master and Corsair being the very best. i say go for a GF480. its a very good card. i'm going for one myself. currently i have 2 GTX295's.
A proper designed case, which are not cheap, have been designed to maximize airflow and in such a way that the heat from Hard Drives, CPU and GPU's are separate which helps keep heat down.
