pci-e 1 vs pci-e 2 on same graphic card?

Question

highlight:
1. motherboard with pci-express 1.0 or 1.1
2. motherboard with pci-express 2.0 or 2.1
3. graphic card pci-express 2 (HD 5770)

with 2 different motherboard, pci-e 1.0 vs pci-e 2.0 with same graphic card.

if i'm playing game like crysis, at very high setting...
and my motherboard is pci-express 1.0 support. then did i get
bad fps(framerate per second)?

some say you wont notice anything,
some say your performance is decreasing like 10 % = 5 fps
so it's true? that using motherboard pci-express 1.0 is will decreased performance much?

Answer 1

from my experience with Graphic and PC game

it's completely different ... i play Crysis both 1 and warhead

in high VGA sitting with Nvidia Gforce 8800GT Alpha Dog 512BM 256Bit(Memory bus) in PCI-EX 2.0

with in problem but with 1.0 you will have some problem with Fram Rating and Resolution

just try and see ...

Answer 2

pci-e 1.0 is a bit slower that pci-e 2.0, but from my experience, you really can tell the difference, unless your using a very high end card.

Answer 3

PCIe 2.0 is an progression over the older PCIe a million.0 usual, and its totally compatible. PCIe 16x refers back to the slot variety (for eg a PCIe 1x slot is fairly short, a PCIe 16x slot is longer). Video enjoying cards use 16x frequently.

Answer 4

it will decrease your performance by 2% which = 0.57fps there is no difference really other then higher bandwidth.
