Last year I planted a Forsythia "Meadow Lark" and was glad to see it blooming the past two weeks. The blooms only grow on old wood so it is important to do any pruning of the bush right after it blooms. If you wait to till fall, you risk cutting off all of the new growth which would bloom the next spring.
I researched the various types of Forsythia and decided on this bush because it grows rather quickly, has a height of 8-10 feet, and has a spreading/arching form. I wanted a specimen plant on the back corner of my house, but didn't want to go with a tree (like a Crab Apple) so close to the foundation. It doesn't look like much now, but in a couple of years, it will be stunning!
Below is a photo I took last spring of a Forsythia bush in Wisconsin:
