mine can take up to 3 mins, my friend has a much inferior PC to mine, i have a i5 2500k, GTX 580, only 4GB of RAM but still, he has a low end AMD CPU and a GTX 550 ti and 4GB of Ram but he loads in about a minute. --- I have a learning disability, it is hard for me to understand technical stuff without clear instructions. Please forgive spelling and punctuation mistakes. Ty.
I get long pre-cache times too, compared to my pal who I play NS2 with we have same processor, 6Gb RAM, he has 2x Radeon and I have a single 470GTX. But I also have an SSD and he doesn't, and he gets into games about 1m quicker then me.
