GTS 450 1Gb GDDR5

I replace PowerColor ati HD 3650 512Mb ddr2 with Gainward GTS 450 1gb gddr5.
After I installed drivers, I notice some problems with optimal settings for COD3, when i succsesfully solve that I have to waith 3 -5 minutes to loading the solo play map!!! afte tooo long loading, it wasn't a problem to play in max rez 1920x1080. My old card was much faster in logading COD3 maps for solo play.

I try to uninstal drivers and to install newest but it become impossible to install newest drivers.
And now i cant use GTS 450!!!???
