my epox 9ny mobo died and I want to keep my amd 64 2x and 4 megs ddr400 and case so I purchased an older asus gaming mobo. the new mobo has sli capability for pci express x16 rev 1. my question is, with the new evga (or xpx or whatever) 9800 gt graphics cards, are the new ones 55nm technology or are they 65nm technology. I need to know because with my 500w ps in my old case the 55nm cards will sli just fine for power and heat. The older 65nm cards are power pigs and will likely overheat the whole rig. new main board is ASUSTeK COMPUTER A8N32-SLI Deluxe. new cards that I propose buying are EVGA 01G-P3-N988-TR GeForce 9800 GT. Are these new cards 55nm? Anyone? Any advice as to a better way to go for sli 1.0 support with other cards? Thanks
