Windows Vista Questions about my Vista with a 64bit processer

So I have a laptop that's rather nice and it's a 64 bit processer that runs vista. I've already had some trouble getting the new IE and I have no idea which one to use since downloading it since it came with like 5 IEs already. So this is a question to ask if there's anything I need to know about my processor of if there's anyone else that has a 64 bit processor. And possibly figure out which version of IE I should be using. Sorry if I posted this in the wrong spot. v__________v

 

Use the 32 Bit IE. I have had some isues with the 64 bit version. I actually use Firefox for 95% of my serfing and us IE only when the site requires it-Like Microsoft.com

 

I use Google Chrome for everything else and IE for other stuff when Google Chrome gives me issues. Firefox gave me so many issues I don't know why. x_x And I love Firefox too!
