I was very disappointed to see my new motherboard i ordered in with quad core 3.1 GHz has only one PCI slot and I'm wondering if you can get a second somehow. I don't have very high expectations for the answers knowing the motherboard has to be compatible with SLI or Crossfire to be able to even use it and they wouldn't make it compatible if it only has one to begin with. I have been looking at lots of gaming computers and a popular setup seems to be two GTX 660 TI SLI that scores equally to some very expensive single graphics cards in hardcore games. Anyways any help would be appreciated and any suggestions for graphics cards in the heavyweight division would also be appreciated.
