Gigabyte GA-P55-UD4P


I would like to buy a motherboard of Gigabyte or ASUS that suppport:

2 PCIe(I'm using 2 graphic cards: HD5770), USB 3(Full) ,Crossfire.

I will buy the i5-750 CPU.I would like to know which motherboard of ASUS and GIGABYTE can support the above.(a min board level)
I'm thinking about the P55 series of Gigabyte but I don't know which one to choose.

The application is gaming.Is 4GB enough? (2 *2GB)

  1. The only way I know of, in the Gigabyte world, anyway, to get two full PCIeX16 slots is to go with the GA-P55A-UD7 - it uses an nVidia NF200 muliplexer chip to get the 'extra' lanes, which will let it do xFire or SLI...

    The 1156 processors only support sixteen lanes off the CPU, with another 2x4 run off the P55 - there just aren't the lanes to begin with! That's always been the difference between Intel's 'P' and 'X' series chipsets; X's just start out with more lane capacity, so there's more to 'go around'. I would think seriously about an X58 based board - Tom's just reviewed the GA-X58A-UD3R a couple days back...
  2. Asus has better USB3 implementation, however as bilbat said, X58 looks like a better match for those requirements. Although 2x5770 won't be limited by 8x/8x.
