Am I the only one that Lion is unusable for due to freezing?

Hello-
I'm sure there are other threads on this, but the forum search doesn't seem to be working for me at the moment.
Anyways, I have a Mid 2010 2.4GHz i5 15" MacBook Pro, with the optional high res screen. After upgrading to Lion, I literally had it freeze on me every 2-5 minutes; it was completely unusable (As in completely freeze, caps lock light unresponsive); I had a 128GB Samsung Sandforce SSD, and I put in the stock 320GB HDD and reinstalled Lion to see if it would fix this issue... Long story short, it didn't.
Don't get me wrong, I like the features Lion has and wish that I could be one of the people happy with it, however for the time being Snow Leopard is much more reliable, at least for me.
Has anyone else had these issues, or should I call AppleCare and get my MacBook Pro looked at? My computer has already had a new logic board due to Nvidia GPU failure, but this was before Lion, so I don't know if this is the computer itself.
When Lion came out, I went over and upgraded my parents' computer, a stock 2.26GHz White MacBook. Apart from being on the slow side, which a RAM upgrade solved, their computer runs Lion better than mine ever did... It's how I expected mine to run. Both of these computers were basically a clean upgrade, with the factory image of Snow Leopard and iWork installed.
Does anyone have any suggestions, or the same experience so I know I'm not alone?
Thanks for the input.

This is a common problem on mid 2010 MacBook Pros. Its a problem with the graphics chips switching causing the freeze esp on login. The fix or workaround (for the moment) is to switch off "automatic graphics switching" (AGS) in the energy saver pref pane, and enable auto login to bypass the login freeze. your machine will be much more stable after that, but battery life will suffer. Hope 10.7.2 fixes this.

Thanks, I will try disabling the auto graphics switching...
However, I already have autologin enabled... freezing there is not the issue. My computer will freeze constantly when just using finder, safari, or at the desktop.
