I am new to techpower but love gpuz, have a issue can someone help? as I own a 9400 GT from BFG, that only i can afford to fit into my extrem slim Dell Optiplex 745 with 285 watt psu. This cards works fine in my system but can i upgrade it to any 9500 GT bios ( for doubling shaders from 16 to 32) it has a 512 MB ddr II ram from samsung ,g96 core and bios 62.94.2c.00. I know 9500/9600 GT are cheap & easy to get but they cant fit in low profile slot on my system. and i cant change system because i love slims with low power consumption that why i bought this system.
