i want to buy a new graphic card but i confused. there is a new gen of graphics cards with a PCI 2.1 bus standard and i want one of this but
my pci slot is 2.0 bus standard. is it work with the new card?
It will work just fine... there is very little difference between the pcie 2.0 and 2.1 interface. The graphics card will be backwards compatible. There are very few mobos out there that are even using 2.1.
