renz496 :
that temperature is normal for GTS250 under full load. and the 250 use less power than 9800GTX+ for the same performance. but there are some manufacturer make 9800GTX+ with only one 6 pin as opposed to the original one that using 2.
@OP
if you have to choose between the two i'd say that GTS250 is clearly a better choice
that must explain why my other GTS250 has two six pin, and is an inch longer than EVGA gts 250. I found that one six pin is not working, useless, and other does work.
they must have used the PCB from an old 9800GTX+ when making my sparkle GTS 250 512 MB. (otherwise use a EVGA model, proper GTS250)
and yes, GTS 250 is clearly best option!
good luck, and enjoy your card.
