psirohi :
sure the 6850 is much better. See if you can find a better brand like sapphire, MSI, xfx, asus or even gigabyte.
That said. Whats your budget like? and your rig like?
apparently powercolor hd6850 is the only brand available in my country, Philippines, im trying to canvass a bit more but for now thats my only option..
Intel Core i3-2100
Elite H61h2-M2
Seagate 500gb 7200rpm
Kingston 4gb DDR3 hyper x blue
ASUS 24x DVD burner
AEROCOOL STRIKE X ONE ADVANCE
FSP Group Everest 85PLUS 600 600W ATX
thats my rig..
my budget is around $165 to $ 170..
