First of all, my specs:
Pentium 4 3.0GHz
1GB of DDR
120GB HD, 500GB external
ATI 2600 HD 512MB DDR2 (AGP)
Mobo - P5P800S
Recently I purchased ATI 2600 HD 512MB AGP and after installing it I noticed my computer started processing much slower than with nVidia 6800 XT 256MB. I went into BIOS settings and tried to change video settings from 256MB to 512MB but 256 was the last and highest there. Does this mean my motherboard doesn't support 512MB video card? I just increased monitor refresh rate from 60 to 75 which increased the speed and looks like it works to its potential, but is there anything else I should do to maximize performace and make sure I get full speed out of this card?
Thanks in advance,
