I had to laugh I have three computers and my other two machines both have PCI- express ports but on my main rig I got a cheaper mainboard and doesn't have it. I laughed so hard when I opened up my case I almost dropped it. I'll just save it for my next upgrade. I don't play games on my older rigs. (core2dou system)
I thought that would give you guys a chuckle. It made me smile.
