Installation Requirements

Well I Am Interested in playing crossfire but I would like some insight before downloading a """70gb""" program, When I bought this computer I Was told not to download things because well. it might break, and well I've been downloading material anyways, the files are important for school ofcourse. so its only word documents, spreadsheets and powerpoints. I have """203gb""" free space on my C drive . Also I have a rating of """excellent""" for my internet.. but usually when its password protected its """great""". the speed currently for excellent is """54Mbps""". This combined with my computers performance statistics being
Processor = 2.2
Memory = 4.3
Graphics = 2.1
Gaming Graphics = 3.0
Primary Hard Disk = 5.4

I know there is another set of important statistics somewhere ...okay found em I have a :
32-bit operating system
My processor is 1.6Ghz
and I have an additional 2gb of memory installed

based on my credentials should I be safe to download such a program and have a lag free time, I know on my parents computer my ping was 51-53 and im not too sure if i should be trying to play with anything more than 125.. I might get my hands on a better computer, but i don't want to screw up the computer that i need and use. If you need any more credentials I can post them if you can tell me were they are located thanks

An opinion from someone computer sauvy would be appreciated.. and if you are someone with limited experience please don't give me a reply

I had trouble choosing a prefix, don't pay it any attention
