hi all

i recently purchased an HP pavillion slimline with a Q8400 quad, specs here: http://www.shopping.hp.com/webapp/shopping/computer_can_series.do?storeName=computer_store&category=desktops&a1=Category&v1=Slim+and+sleek&series_name=s5380t_series&tab=review&#defaultAnchor

its has a PCIe x16 slot for the graphics card and currently has a nvidia G210 in it. I'm looking to upgrade but realise my choices are limited as 1) its a mini tower and 2) i think the PSU is only rated 220w.

what are my choices for cards? id like to get something that has comparable performance to the HD4850 or 9800GT. would i have to upgrade the PSU?

thanks!
