help me decide

ok...first things first....my specs:
Athlon 64 4000 @ 2.9gh on air (wahoo)
Corsair xms pc3200pro 1gig @ cas 2
EVGA motherboard nf41
EVGA geforce 7800gt oc (470/1100)
WD 160 gb sata hd
sony dvd rw
sony dvd rom

Ok...heres the question for you with more knowledge than me. I want to upgrade....would I be better suited to getting the 7900gto or get another 7800gt and go sli.....or......should I upgrade with another gig of corsair and wait for the g80? What is the best bang for my buck in this situation. What I like about going with the 7900gto is the evga step up program.......please help........

Another gig of RAM isn't a bad idea, but if you go with 4 512MB sticks you run a good chance of hurting that nice overclock you have going. I'd sell you current RAM, buy a 2x1GB kit and wait for DX10 cards. Your 7800GT should so just fine for a few more months.
