Don't drive summer tires in the winter. It's 200% stupid, you can do it, but its dangerous. I've been there, and yes its possible but it was only due to circumstances. If you're buying tires for all around performance summer & winter, just get a nice set of all-seasons. I had the continentals mentioned above on my evo for 2 winters, half a summer, a few falls and a few springs. They're great all-around all-season tires.
Depending on what size you want they're around $100/tire, pretty great bang/buck

I've heard that the Sumitomo HTR+ all-seasons are decent too, but I've never used them personally.
Others will have plenty of opinions to add to this discussion (kracka) I'm sure
