Why is PCIe 2.0 so important to you ?
P35 is not PCIe 2.0 yet all current 'PCIe 2.0' work flawlessly on it.
It is a well known fact that even with PCIe 1.0 , full bandwidth is STILL not utilised,that PCIe 2.0 is necessary.
Frankly, your requirement of SLI board has made it difficult to choose a perfect board which is the best bang for the buck.
IF SLI goes out of the equation,suddenly there are so many options !
Compare Abit IX38 QuadGT and MSI P7N Platinum and tell me honestly, which board impresses you more.
If SLI is mandatory then i would say get the 790i and nothing else. If you are game with it, i will suggest you decent memory for that board.You can go with EVGA 790i or XFX one,whichever you like.It will be an expensive affair though.
This is what annoys me, its like Nvidia is dictating the terms here.
Meaning, if you want SLI ( Their super elite,awesome, out of this world,droolworthy multi GPU technology) then you have to compulsory buy their crappy, pathetic chipset based motherboards too.The one that is really good is so obscenely expensive.Even Intel flagship chipset isnt that expensive.
Here is a simple comparison,
Gigabyte X48T-DQ6 is cheaper by a healthy 20$ or so compared to EVGA/XFX 790i Ultra SLI. Gigabyte has much better build quality and is more feature rich compared to EVGA/XFX boards which are just reference boards.
No thanks, when i am spending my money, i would love to have my options open,thats the reason i love Crossfire.Intel chipsets right from P965 support it, AMD chipsets obviously support it.
I dont think SLI has so much compatibility as Crossfire.
This is just my opinion though.
I hope you get my point.
