The 5850 would definitely be overkill. Grab the 5770 and plan to Crossfire it if/when you buy a 1080p TV/monitor. This way you can save some money now and later when the prices drop without having to sacrifice performance at any point.
Unless you're planning on getting a 1080p TV/monitor soon. Then it would be better to get the 5850. Since the 5770 costs essentially 1/2 of the 5850, it would be better to leave the Crossfire option open.
thanks admiral. yea im going with the GIGABYTE GA-790XTA-UD4 so i can have that option open to me in the future.
i love having the large picture in front of me and haven't really thought about purchasing a new monitor for some time. i suppose the 5770 would be the best for the bang at the moment with the option to crossfire later on. thanks!
thanks again for your quick responses. i think i will go for the 5770...any particular unit i should be looking at since i don't mind spending a few extra bucks since i'm saving about 150$
