Hello, just wondering does any Graphics card today exceed the pcie 16x v1.0 bandwidth yet as in bottle necking the Graphics card? like a Ati HD 3000/4000/5000 series?...........say you run 3Dmark06 with a HD5870 on a pcie v1.0 and get 20,000 points....then run the test agin but this time use pcie v2.0, Would it score any higher?? :??:

pcie x16 v1.0 is the same bandwidth as pcie x8 v2.0, which gives maybe a 2% performance loss (not noticeable/within margin of error) for the 5870

however, as you scale up into more demanding cards, and especially when it's a more demanding game, the pci-e 2.0 will transfer the needed data from the mobo to the card much faster than pci-e 1.0

i do agree with mindless728 about how small of a drop you will detect
