lowest price and good performance is partially contradictory. The strongest low profile card besides the asia only low profile version of the 6850 is the low profile 7750 by HIS or sapphire. but of course, being the strongest, has the highest cost.
sorry for late reply,my earlier graphic card was GIGABYTE HD 5450 512MB ddr2 lowprofile,but last 2 month the vga cable for the graphic card broken so I decide to buy a new one.
When i connect the vga cable from the monitor to the graphic card the fan only worked but the mnitor screen display blank.
