Critique Budget Upgrade

[bruins004]

Hey all,

The following components I already have:
Xtasy X800 (This will be replace once R600 comes out)
Creative LIVE soundcard
2 x 1GB of DDR2-800 Buffalo Firestix (5-5-5-15)
250GB WD HD (IDE)
DVD RW Driver
DVD / CD Combo Driver
NZXT Nemesis Case (w/ 3 120mm fans and Temp Sensor)

Now this is what I am going to buy:
AMD AM2 X2 3600+ OEM ( http://www.newegg.com/Product/Produc...E16819103 036 )
Biostar TF550 ( http://www.newegg.com/Product/Produc...E16813138 026 )
Combo Price: $150

OCZ GameXStream 700W PSU ( http://www.zipzoomfly.com/jsp/Produc...tCode= 316505 )
Price: $104.99 AR
--------------------------------------------
TOTAL : $255

I am looking to spend as little as possible on the CPU / Mobo.
Would another one serve a better purpose.

I was looking around and realized that AMD is set to drop prices on April 9th...
Would it be worth it to wait and would they drop the prices on the X2 3600+?
