But I just don't get it as to why the X1950xtx is more expensive than the X2900XT where the latter is the latest card?

And which card is best to be used with windows xp?

id say an 8800 gts but the 2900 is also a good contender ( i just like nvidia more )

if you dont want to spend that much, i have the 7950GT KO 512 and i love it, the only thing is it doesnt have DX10 support. if you dont need dx10 i highly recommend it

But I have heard that the X1950XT 256MB is faster than the 7950GT KO 512MB(even after superclocked).

they will give almost identical performance according to most reviews i have read. i bought the nvidia card because i use the 650i chipset, and i have always had good experience with nvidia.
