I have a mid 2010 Macbook Pro 13" 250 gb hdd, 4 gb RAM and 2.4 GHz Intel Core 2 Duo running Lion. It runs fine, but slows down when I'm doing a lot of stuff at once. I'm going to do a clean install of Mountain Lion on my Mac when it comes out and I was wondering if it would be worth it to upgrade my RAM to 8 gb (2 X 4gb)? Also, is it possible to replace my hdd with an ssd? Thanks.
