Hi, I have bought a geforce 4 ti 4400 128 mb ddr. I have installed it in my pc. Which is an amd athlon 1,1 ghz pc with 256 mb sdram 133 mhz. The problem is that my card isn't functioning very well. I have to run games like ut2003 and battlefield at low settings. Even than i only get framerates around 30 fps. I know it is my pc that makes it perform bad. Now i wanted to ask how i should upgrade. I thought buying a new mobo and ddr ram. Unfortunately i don't have this money available for now and the upcoming months. I would like to know if upgrading my ram to 512 mb should make any difference? I don't know much about hardware so maybe you have some tips for me to get better performance. I also would like to know what aperture size means? it is in the bios. I didn't changed it, but it sais 64, I thought maybe it has to be 128 because i have an 128 mb card. Thanks in advance for your help.
