In 22 days time you could gate an athlon x2 in same price you'r paying for that atlon 3700
Other than that, awsome build, enjoy it!
And in 22 days time you would also have the option to go with the E6600 Conroe which all talks about, that supposed to kick *** for a long time.
Hope this helps
BTW, i'd spare the money on the GTX and get same card only GT and OC it to a GTX clock speed, and in the money I spared + maybe a little add on i'd ge a **** of a custome dangerden cooling kit!!! heh..
