am running socket 939 not am2 so cant use em i'm afraid.
cannot expand ram any further, just sold 2 x 1gb cos board would knock the speed down past 3gb mark.
sorry its actually ddr 500 250 in dual channel

as you started with this thread with a psu question i would get as big as you can get. may be worth the outlay as you'll never have to buy another for a long time and you can upgrade as you wish.
just my opinion.

533mhz? or what? Be more specific on the RAM.. because your system literally blows if you own bad RAM, especially with CrossFire.

Also, how much did you spend on everything?

That's an interesting Opinion.. although I made it tight on purpose..
For one main reason:

I hate the electricity bill.

EDIT: Sry for the double post.

its a ddr 500mhz which translates as dual 250mhz.
its ballistix which is renowned for stability and quality so overclockable too.

now to money ouch.
a8r32mvp delux £100
amd fx 60 socket 939 £195
2 x 1gb ballistix ram £165
enermax galaxy 1kw £200
2 x x1950xtx £450
dell 24" monitor £600

about £1600

may be daft here but i think the psu only uses the power thats needed so am not sure if it'll be too much of a drain untill you load the pc up with power hungry bits.
may be wrong i aint no electrician.
