With the Witcher 2 specs being released it appears I really need to upgrade my current graphics cards (two crossed over). However, I was hoping someone could help clarify some pci express x16 and pci express x16 2.0 compatibility questions.
Current build (links to Newegg parts):
Mobo:
ASUS M2R32-MVP
Processor:
AMD Phenom X4 9650 Agena 2.3GHz
Current Graphics Cards:
2 Radeon HD 2600XT 512 MB crossed over
Windows 7 64 bit, Rosewill 500W PS, 4gig of Ram, monster sized case and two HDDs.
My problem is the mobo is PCI Express x16 and not 2.0. I looked it up and and some posters help me confirm that the 2.0 is compatible with my current mobo. However, it appears that the 2.0 cards will not be able to perform at peak performance because of the bandwidth limitations in 1.0.
What I was unsure of is how the limitations of the 2.0 in 1.0 mobos are? Will buying a low end 2.0 graphics perform the same as a high end 2.0 graphics card because of the limitations of my mobo/chip set/bios? Take this example, SAPPHIRE 100283-3L Radeon HD 5770 1GB 128-bit GDDR5 for
$140 vs. HIS H467QR1GH Radeon HD 4670 1GB 128-bit DDR3 for
$70. Will the extra money for a higher quality card really make a difference in a PCI Express x16 1.0?
