to be honest it all depends on the game and the size of your tv . eg metal gear at 720p looks 10 million time better than prince of persia at 1080p purely becuase the graphics are so much better
in a nut sheel hd ready means 720p 1080i . while full hd means 1080 p and really will give the best picture possible. only a handfull of games support it . and in my eyes gt5 and wipeout are the majors (due to reasons above )
is it easy to see the difference between 720p/1080i against 1080p?
Depends on the size of the TV to be honest.
'HD Ready' effectively means a TV that must support a minimum specification of 720p, that is 720 lines of vertical resolution (usually 720 x 1280), amongst other things.
'Full HD' effectively means a TV that support 1080p, that is 1080 lines of vertical resolution (usually 1080 x 1920), amongst other things.
For gaming, obviously the higher the resolution the more effort the PS3 is having to put in to display everything and hold graphics in memory etc.
As has been stated, there are fine examples where 720p is a better choice because the amount of graphical detail and fluidity of movement is much easier to coax out of the PS3's hardware than running it at 1080p. For movie playback of Blu-rays etc though, the hardware can handle the playback fine, so it makes sense that 1080p is the standard whenever possible.

Just to confuse matters, HDTV manufacturers are now branding their 1080p sets as HD Ready -1080p on recent sets.
I think the Full HD badge has now been dropped by alot of manufacturers.
Ok, i think im gonna buy a hd ready one.. i cant spend very much cash (not more than £600)
i'm gonna get a 27/32" one.. any suggestions?
27/32" you have no real need for 1080p as the quality difference between 720p and 1080p below monster screens 50" and above is negligible.
just stick to a quality brand such as sony or panasonic (pioneer if its in your budget) and get one you like most.
people who say 1080p is a vast improvement over 720p on say a 32"panel are either misinformed or just lying (i currently have a 42" panasonic viera 1080p,but have had a few 32" 720p sets in the past.
if you want a good quality tv at an affordable price look at samsung (they use sony components). their sound isn't great but if you've got a home conema setup that shouldn't matter plus they have fully customisable settings and a game mode already set up.
other than that i would look at lg cos their systems are pretty well setup. Avoid sony to be honest as you're paying a p[remium for the name.
for best prices look at amazon after checking out the actual set in currys/comet (you can normally save about £100 through amazon).
