SLi or Crossfire Asus Rampage II Extremem

[cm123]

comment first - Asus Rampage II Extreme board is deeper than normal, you loose wire path in Antec Twleve hundred because so long goes to the drive bays (many others no works) - also if using tri-sli or crossfire, or using a double slot PCIe card in the PCIe 3 slot, will not work in many/most cases with power supply on the bottom, no room for the card - like the CosmosS no fit even (and thats a big case).

2 questions - so if I switch to ATI HD4870X2 - does/if I put 8800 GTS 512 in another slot, as I able to use that as physX card then even though primary card is NOT Nvidia?

and other is below...

Change power supply if you want to run a HD 4870 X2 in CF, or dual or tri-SLI options

why would i ever do that???

few if any power supplies top the quality of Mushking Power Supply - 800W of good supply has proven very well for me...

as fyi... could not get physX to work when had HD4870X2 as primary card and 8800GTS as 2nd card - sure just set up I have as right off driver issues it seemed

no matter sticking with single GPU solution and got my hands on GTX 285... can't say its micro-stutter or not, can say do notice things just not 100% correct (as smooth) when playing FPS with SLi/Cross-fire in some of the games I play...

If you're planning on a single GTX 285 that PSU is more than enough, as the 285 is supposed to use 189W max, which is ~40W less than the GTX 280 and also slightly less than the 65nm GTX 260 and 4870.

Also, you can't run an ATI card for graphics and an Nvidia card for PhysX in Vista, as current WDDM restrictions only allow for 1 graphics driver.

Which reminds me now that Windows 7 Beta is here, can anyone running the Beta with both an NV and ATI part see if Win7 accomodates more than 1 WDDM driver?

good point - windows 7, would be pretty cool if that worked...
