I have become totally confused by all the hype so here goes.
I have a Gateway GT 5670 it has, one PCI Express ×16 slot.
1. I have DDR2 RAM in my PC. Most cards I see use DDR3 does that make a difference?
2.As stated I have a PCI Express ×16 slot. I see PCI Express 2.0 on quite a few cards. Does this mean it'll be compatible with my PC?
3.Is there anything else I need to know that I haven't asked due to inexperience?
