DUDE. You are so deep i can't even see you
.. The HD4650 beats the hell out of the 9500gt. you CANT EVEN COMPARE IT to something as low end as a 6150se .. In conclusion.. HD4650 wins cause its dedicated DDR2 memory. 512MB of it.. + DX10 support and extra shaders. the list goes on. if the 6150se is 1/10 then the hd4650 is a strong 6
