Is 1080p really worth the money for gaming?

I am planning on buying anew tv and I have 2 I am deciding between. One is a Scepter 32 in. 720p for 249.99. The other is aScepter 32 in. 1080p for 329.99. Will the extra 80 bucks be worth my money? I will be doing a lot of gaming on the ps3 and I want the graphics to be awesome.
