I almost jumped on the 305T when it was on sale. The size is great and the resolution would be fantastic but these old eyes aren't what they used to be and i find the text on the 275T+ 27" @1920x1200 MUCH easier to read across the desk. I have not noticed any lag or ghosting in the few games I've tried on it so far - but I'm only a casual gamer so I may not be the best judge (though this zippy machine and bitchin display might get me playing a bit more often
).
