As already mentioned don't get that Rosewill PSU!!!. At stock speed that E8200 is perhaps a little underpowered for that 4850, but you can change that with a mild overclock and overclock it will . I say go for it, with a better PSU of course. The Antec EarthWatts 380 will be sufficient. If you plan on using crossfire latter on down the road though you will need something a little better.
