Hey all,

So I have had my M18x R1 for about 2 years and its running great still.

here is my current config.

M18xR1, i7 2760QM, 8 GB DDR memory, 2x 580m SLI

So I was thinking of upgrading to the 2920XM CPU...if I'm not going to overclock is it worth it?

Was going to upgrade the 580Ms to 680Ms anyone have any issues so far?  I know with the R1 I will have to do a vBIOS flash to get the 680s to work.  Also do the Dell 680Ms come SLI capable or not?  

Any help would be great

Thanks!
