nforce 680i and 780i

[jds21]

I was wondering what the bige difference is between the Nvidia nforce 680i and 780i chipsets. As far as i can tell, there doesn't appear to be a worthy difference to justify the double cost of the 780i.

What are some of the big differences that make these board better? I really don't want to spend such big money on one but I was wodnering if thetre is anything worth the cost

I was looking at:
XFX nforce 680i LT SLI (AU$280)
XFX nforce 780I SH9 (AU$415)

My system is:

Intel Q6600
2x XFX 8800GT 512MB in SLI
4GB Corsair DDR2 PC-6400/800 (4xXMS2 1GB) TWIN2X2048-6400C4 Ram
2x Seagate 500GB SATA II 32MB 7200rpm HDD
Pioneer SATA 215BK Dual Layer DVD-R/RW
ASUS Lightscribe 18x SATA Dual layer DVD-R/RW
Thermaltake ToughPower Pro 750w
D-Link DWL-G520M Mimo 108G
Leadtek DTV2000H Hyprid TV Tuner
Zalman CNPS9700 LED Copper heatsink
Soundblaster X-Fi Xtreme Gamer Sound Card
Antec P182

Ot if not, also suggest other chipsets able to run SLI that will suit my system

Thanks,

Main difference:
pci express 2.0
TRI SLI you can actually do this with 680i but you'll need to get your own 3 way sli bridge.
45nm support
3 pci express all at x16.

Honestly, I don't think that justifies the price difference. I understand the the 680i is dating technology now that the 780i has come out but I don't think I have much choice because the only other SLI intel mobo is the P5N-E which is worse than both.

Which mobo are you using now? I didn't see it in the list you provided.

Clarify... this is not the system I am using,... it is the system I am building...

Right now I'm using a Pentium 4, Intel Mobo system so you can see why I wish to upgrade

Although I must say, looking at your specs.... they appear quite similar to mine (better of course but close enough)... what is your mobo like? Have you overclocked, if so, how well does your mobo cope?
