Im trying to find a motherboard that could run at x16x16 in crossfire mode because in the future i will crossfire or Sli, depends what card i get at the end of the month, also accept i7,i5,i3 CPUS and Sata 6gbs. dont really care for USB3 i can live with slow speed on USB as long as i get tip top performance on PCIe and Sata
I have seen one motherboard like that ASUS P6X58D Premium but I'm not sure if it can run x16x16 in sli/CF and its also a little pricey. I wouldn't want to spend more then 250$ and still have it for long way to come with maximum possibility to upgrade components without having to buy new motherboard in a year and half when i want to buy new processor or new graphic card.
If you read the specs, it says: 2 x PCIe 2.0 x16 (single at x16 or dual at x8/x8 mode)
If you really need x16/x16, then get an X58 chipset motherboard. The Asus P6X58D Premium meets your requirements: 3 x PCIe 2.0 x16 (at x16/x8/x8 or x16/x16/x1 mode) However it requires a socket 1366 CPU like the i7-920.
