lol - G80 SLI rig... "gaara & nubius" will have a field day with that one.
nah, most people know our stand on SLI....especially considering gaaras made a formal Anti-SLI sticky lol.
Anywho...I don't know why I didn't even notice this earlier...but you went and got a new mobo and that hefty graphics card and stuck with 754? Seems like you shoulda just gone with Socket 939 at that point, but I suppose since that particular board is utilizing the nf4 chipset then it'd be aright.
Doubt you'll be making that SLI rig any time soon so 2gb wouldn't be that bad of an idea, you just gotta decide if you REALLY need it right now because I'm guessing you'd mainly want it for games like FEAR, BF2, etc..etc... those massive RAMhog games...
so basically you gotta ask if it's REALLY worth the money just for that extra little smoothing...which I figure SHOULD be smooth anyway considering it's smooth on my system and your card is better.
