Upgrade/ hot rig?

[ObiwanShinobi]

So right now my rig is composed of:
CPU: SD [email protected]
MOBO: DFI Lanparty sli-dr Expert
VIDEO: BFG 7800 gtx (might be able to get 300 dollars for this, if so what should i buy? the xfx 7900 gt, extreme, XXX or which one?)
RAM: 1gb pc3200
HD: WD Raptor, 160 maxtor sata, 120 seagate IDE, 200 IDE
CASE: Silver Thermaltake armor case
cooling: 250 dollar watercooling setup

I was wondering when AM2 comes out should I spend a butload of money buying a whole new rig or just wait till somthing better comes out, because how good is my rig at the moment?
And if i get 300 dollars for a new video card by selling my 7800 gtx, i might be able to add some more to it, is it really worth the extra 60 USD for the 7900 gt XFX XXX?

I'd rahter Invest in a dual core cpu then stronger video card ....

First order of business is to upgrade to 2 GB, then look at the video card. You are running at FX-57 speeds now so going to a dual core will not get you anything but the ability to multitask better and improve 3DMark06 scores.

I would wait to upgrade to a new socket.
But $60 to upgrade to the 7900 GTX seems like a good thing to do. JMO.
