T61's kinda on the way out now despite 5 years of loyal service it's hanging
in there but not much life left in it
prob go for T420/520 next ddr3, i5 etc...
Get a Samsung 830 or crucial M4 ssd, the best for the money and have far surpassed intels efforts
Side note: if your still looking at T61's if you want to fit a T9300 in there make sure you get the
right FRU as some motherboards won't except anything higher then a T7600
They will all take 8gb of ddr2 800mhz...
