My system: CPU- AMD PHENOM II TRI CORE 720 Mobo- ASUS M3A79-T DELUXE GFX- 9800gt hdd- 500gb sata2 disc drive- dvdrw sata Ram- 2gig Wireless card With a 500watt psu running it all would i be able to replace the 9800gt with the 4890 without problems?

There are many good ones that would be able to handle a 4890, however most of them are cheap and beaten by good 400 watt PSUs or they are rated at peak and are only really 350watt PSUs.

A 4890 would probably be stressing it a bit. If you want to crossfire down the line(you have a great board to do so) then get this one http://www.newegg.com/Product/Product.aspx?Item=N82E168... If you never intend to run more than a single 4890 then a 550vx will do fine http://www.newegg.com/Product/Product.aspx?Item=N82E168...
