These card are of pretty high standards of mid-range classification so i am afraid that they take the whole system with them. I have hp dc 7900 convertible minitower pc whose product number is kp719av it has a core 2 duo E6550 2.33 ghz , 2gb ram DDR2, 80 gb harddrive when i bought it. NOTE: I HAVE UPGRADED PROCESSOR TO 3.0GHZ.RAM FROM 2GB TO 4GB AND HARD DRIVE FROM 80 GB TO 250 GB.PLEASE REPLY FAST PLEASE!!!!!!!!!!!!!
The cards are bottom of the barrel actually.
The 6670 in ddr5 version is the superior choice out of the three.
