I have two geforce GTX 480's but I have a GA-P55A-UD4P mobo, does that mean, since there seems to be one 16x lane that the two cards at 8x would slow down a lot? Sadly I just found this out after I placed an order on my rig, but I fid out soon enough I could cancel it and try for the X58 chipset. the specs on the rig I got are:

also if I do stick with this I plan on overclocking the CPU.

More about geforce 480x p55a ud4p mobo mean
  1. Your board supports both SLI and CF,so you can use your cards on it(on dual 8x mode)
    "The GA-P55A-UD4P still has support for all of Intel's socket 1156 Core i5 700-series and Core i7 800-series processors, can be installed with up to 16GB of DDR3 memory at speeds of 800/1066/1333/2200 in four DDR3 memory slots. The board supports dual-videocard SLI/Crossfire gaming configurations in a x8/x8 PCI Express 2.0 arrangement, or a single videocard in x16 mode."
  2. I know it supports it but does it limit the power of the cards?
  3. Not much,dual 8x is pretty good for SLI/CF configuration and perform closely to dual 16x
  4. ah okay, so I should be good then. thanks for the input!
  5. you are welcome :)
  6. The only detriment to your set-up is when you ever use USB 3.0 it will not function at full speed.
    Personally i wouldn't be too concerned if your main purpose is gaming on your rig.
    From what i understand the USB would perform slightly better then USB 2.0 anyways just not full USB 3.0.
