Review of Mushkin HP-550 (550W)
http://www.jonnyguru.com/PSU/HP-550/
Not so good voltage ripple!
IMHO my Antec NeoHE 430W (made by Seasonic) is stronger than that 550W...
U can't unlock 7900GS
U can read some more on VR-Zone

P.S. U can try to volt-mod it, they say it can be done the same way as on 7900GT
No, Intel s775 (DDR2) is allways @2T so there is no diference 2x1GB or 4x512MB
But with AM2 or s939 it is better to use 2x1GB because of CPC (CR) 1T
Now there R some CPU's that can push 4 double sided RAM @1T (but it is usually up to 200MHz (DDR400) or a bit higher)
