I really need help here. I was decided to buy an HD 7750 but i have read this article (http://www.overclock.net/a/the-final-answer-to-the-controversial-pcie-x16-version-compatibility) PCI-E 3.0 is not "fully" backwards compatible with 1.0/1.1. The article said that it depends on what Gpu you would use in a 1.0/1.1 Pci-e if it will be compatible. AMD 7000 series or newer cards are not compatible with older systems like PCI-e Slot 1.0/1.1 and Chipset G41 and previous chipsets.
The article said this "We all know that the AMD Radeon HD 7000 series is extremely power efficient. Having said that it comes at a cost. This power efficiency comes due to the new electrical interface featured in PCIe v3.0 and 2.0 slots and is ABSENT in PCIe v1.1 slots. Hence they are NOT COMPATIBLE." Please if you have time read the article, it has credible source.
On the other side, Nvidia Cards are more power hungry cards because they maintain the compatibility of PCI-E slots (also said in the article). AMD 7000 series cards are
So, is PCI-e 3.0 slot really backwards compatible with 1.0/1.1?
My specs
CPU Intel Dual Core E5200 2.5ghz
GPU Hopefully HD7750 or i will buy GTX 650 instead (Current gpu is onboard Intel G31/G33)
MOBO Asus P5KPL-AM (PCI-e x16 1.0 slot, G31 Chipset)
PSU Corsair VS450 (Soon. Im planning to buy this with the HD7750)
