A word of caution here: the mid 2010 MBP were the first machines to use lead-free solder. The solder has a history of being brittle and failing. I had a logic board die on mine. More recently, I went to replace a very swollen battery, and bricked the machine. The battery replacement is an easy install for someone with a lot of experience, so don't write it up to a ham-fisted operator.
It was effectively a desktop, so no travel banging.
I did bring the machine in the Apple Store, and multiple geniuses had a look. It was one of the last models you could have a matte screen, and they all were hoping to keep it alive. Fans would spin, etc. No luck. As much as I love the design of this MBP, it's now sitting in the museum. It's just not cost effective to repair.
YMMV. My only objective in sharing is to let you know you're skating in grey. There's a chance, what would seem like a simple upgrade, may have dire consequences on this vintage machine. You may want to take an extra moment to think if it's worth investing money in this machine and putting the money forth to a new one.
