What is your current graphics card?
also, remember, even though you'll have that nice new shiny graphics card, it's going to be hurting when DX10 comes out. if your current system is good enough, then wait and save. There is no point getting a high end right now.. as dx9 is nearing the end of it's days.
Me on the other hand, I NEED the upgrade, but since I don't want to spend a lot just to have to upgrade to dx10 later, i'm going mid-range (7600GT)
and personally, I don't care for LCD monitors. Thier nice, yeah.. but unlike some other people, I dont mind big CRTs, as I have a big desk. (and a smaller wallet)
