I'm about to upgrade my system and need some expert advice. First I'm wanting to upgrade my cpu to a Q9450 45nm quad when they become available. I'll be keeping my DDR2 memory . I having problems selecting a mobo . My choices are either a 780I , P35 or X38 chipset mobo. In my current setup I have 2 8600GT in sli and as you know it's getting quite expenseive to keep buying two cards every time you upgrade. I would like to know if SLI vs price performance is worth the extra cost? If I can get decent performance from one good card say a 8800gts 512mb ( G92 ) then my board choice would be down to the P35 or X38. Please help I need all the suggestions I can get before I drop this money on my new system. Thanks and bye the way I'm knew here and would like to say hello to everyone.
