That's my card(s)(I'm planning to be running 2 in SLI; one's arrived and one's in the mail). Both Nvidia and MSI offer drivers. Nvidia's drivers are newer and Windows 7 compatable (which I'm using). MSI's are a version older and only Vista compatible. Which should I use? What will I lose by only using Nvidia's (first build, sorry, not familiar with drivers at all)?
