754 is dying. Get 939 cause its faster and better for future upgrades. 754 is cheaper but you will regret it when you want a FX and you have to get a new MoBo.
you can get like a 3800+ s754 though, which i'v heard arn't that bad at all.
which, is what i'll have to do if i don't want to spend for a new mobo.
but, i got the s754 cause it was cheap with some decent power.
it will run my games at 1024x768 w/ 4xaa & 4xaf and source i can top out w/ 90 fps on the video test..and runs smooth in the game. ofcouse, my card had a little something to do with it.
but...i do know that s939 is the future proof for a while now. but...like i've said before...i don't need the top of the line to be happy playin' a game....i just need to place first in TM and have the most kills in CS
