Locked myself out of my computer?

I swear I'm such a dumbass I was being all cocky b/c my sister figured out my password so I changed it and made the password hint "hey you get off my computer" but I can't remember what it is. I have a Lenovo with windows 8 and I have one of those photo passwords set up, but I got it wrong too many times because the lines I was drawing weren't exact (I do know my photo password, if that helps) so basically then it auto sent me over to my typed password and I ant remember that one. It is not my Microsoft password. If I click the reset password button it says I have to enter a password reset drive. Do I need to take this to the store, if so which store? Or is there another way around this?

Good graphics cards for 250W max?

I have a Lenovo H520 computer with a 250W max power supply. It has 6G of ram, 64-bit operating system, and a 3.4 gHZ processor. I'm looking to upgrade the graphics card, and I was wondering if there are any good ones of at least 1 GB that are fairly cheap, but reliable. It would be primarily for gaming, but I don't need one of those $5600 ones, just a nice reliable one of at least 1 GB. Also my computer requires a slimline graphics card, or one capable of becoming one. Thanks so much for responses and if possible, links would be great!
