I'm having a struggle on what way I want to go. Nforce 780i + two 8800 GTS + DDR2 or Nforce 790i + 9800GX2 + DDR3. The latter costs more obviously and I'm building new, not upgrading so I'm not sure what way to go. I'll want to game hard on this. I was also thinking of the X48 chipset and a single 9800GXT, but this gives me no chance for SLI.

HELP!

If SLI is important to you i would go with your first suggestion. Otherwise get an intel chipset board. X48 & DDR3 is still too expensive IMO.

How big of a monitor? If your going with a 1920 x 1200 or 1080p resolution or lower, then I'd say go with the first option. If your going for a 30" with 2560 x 1600 your probably better off with 8800 ultras because of the extra ram.

DDR3 is still very expensive as is a 790i board so it's hard to recommend. The cost to performance gains aren't there. If you're going to OC heavily a 790i might be a better choice in that regard over a 780i. The chipset is a little newer and runs cooler. As lduguay said a lot of people also skip SLI and go 9800GX2 paired with an intel chipset as it is quite comparible to SLI performance but Intel chipsets seem to work a little better with Intel processors.

All I can say is see sig for my choices. :D

Off topic: @lduguay: What kind of voltage are you pumping through your CPU / NB to get that processor stable? I've been contemplating getting a Q9450 instead of the Q6600 because of the extra cache and performance per clock. I'm not sure if I want to push the FSB very high but it looks like your doing 1700FSB. How long has it been running stable like that?
