I m not much of a EQ player, so I dont know abt its graphics. But I dont think they'll be matching that of Doom 3, Half Life 2 or FarCry etc. If you were playing any of these, yes you will see a jump in performance, bcos those 2 cards are the extreme. As far as EQ2 is concerned, you will definitely get more FPS with those cards and you'll be able to run game with all enhancement goodies on (if there are any, like AA, AF etc). But then the question is whther it matters in EQ2 or not, not to forget the $$$ tag.
It really is up to you. The GT's 16 pipelines to the X800's 12 is a pretty good factor to consider but when it comes down to it, which do you prefer.. Nvidia or Ati?
Both will give you playable FPS at 1200x1024 (not sure on 1600x1200, it is quite an intensive graphics game) considering the amount of options it has for graphics tweaking. IMO, i'd go with the GT unless you can fork an extra 100 for a X800XT, but I'd say go with the GT.
I would suggest GT for the money, but I would suggest X800XT if you want to go all the way. My reasons is that the GT is as fast or faster thant he XT in OpenGL games and only about 10 fps behind in most others. But the XT is faster all around, especially in HL2 because nvidia kinder got screwed over with the FX series so valve concentrated on ATI.
You should be able to get an X800xt for well under $500, I got mine for 469 over 3 months ago.
