Ok, so im upgrading to a 6770 on my old desktop pc, however the 6770 has PCI express 2.1 and PCI x16. Now I know that my motherboard has x16 but not sure if it has PCI 2.1. Does it also require to have PCI 2.1. Please let me know.

thats the problem xD i want to get a good card without upgrading the psu and the 750ti needs an external power connector. What do you think about the GT 720? Will it run fine with everything?
