bradley26:i have the sony STR-DG820 will i see a better picture than the ps3?
Depends. For blu-ray 1080p/24 pictures, you'll struggle to notice any difference. For DVDs, PS3 is a decent upscaler although there are better machines. As your TV is only 32 inches, the difference may not be as pronounced.
I would strongly recommend you to take your PS3 along to to your dealer & arrange a demo to compare.
