If you can get a passively cooled GF3TI200 ($90?) then this is certainly the fastest passively cooled option. Rad9000/9000pro ($80?) is relatively close behind and like GF3 cards it sports full DX8 hw functions which is VERY nice for some current and all up coming games. GF2MX are a bit dated and slower than your GTS, but MX400 ($40?) cards are cheap and aren't unbearably slower. GF4MX420 ($70?) are the best match for your GF2GTS card BUT sport better image quality, AA, dual display, TVout and hw DVD playback. Go by your budget and needs, BTW what CPU are you running? This makes a big diff as to real world perf with diff gfx cards.
