If your computer support x64. Absolutely without a doubt! Go for it "IF" you have at least 4gb of RAM installed! If you have only 1 or 2 gb of RAM installed Windows x64 will be very slow and sluggish
And having a 32 bit version of Windows can't use more than 4gb of RAM you most likely don't even have any more than 4 gigs of RAM installed, so BEWARE you might not see any improvements in performance switching to x64, and maybe a little less, so you're definitely going to want to upgrade the amount of RAM installed, preferably to a matched pair (2x4gb= 8gb to run in duel channel mode) to at least 8gb. You should see a HUGE boost in power, stability, and track count.
And of course 2x8= 16gb is so much better (if your laptop can support that much RAM), especially if you use sample based DXi's like Rapture Session/Pro and Addictive Drums and or the likes of.
