[ARTICLE] Converting x16 GPU into x1 GPU
Convert a PCI-E x16 Video Card to Fit a x1 Slot with a Diamond Cutting Wheel

I think all of us are familiar with the idea of 'forcibly' inserting an x16 card into a x1 slot.

The article describes a scenario where the card itself is cut to fit into the slot (and certain pins are shorted to fake x1 card status).

It is mind-boggling to me that this doesn't cause a performance degradation. Does the cited person simply not realize that his card is being bottlenecked or is he actually correct?

Probably due to the fact that the card was talking up no where close to the x16 slots bandwidth so performance isn' t hindered much. Also don't forget the difference between x16 and x4 is only ~5% so I'm guessing performance decreases logarithmically.

I'd use something like this long before I try cutting anything, whether it be the motherboard slot or the video card's PCB:
Amazon.com: StarTech.com PCI Express X1 to X16 Low Profile Slot Extension Adapter (PEX1TO162): Electronics

As for performance, there's definitely a drop:

If you look at the original post, he used Team Fortress 2 with unknown resolution or setting to claim there's no problem, and it's a GeForce 8400GS, which can probably be beaten by Intel 2500 Graphics...
