Hey guys,
I'm not quite at the point where I want to build a whole new system, but I've been thinking of upgrading my video card. I have an Asus Rampage III Extreme motherboard (Intel X58 chipset). It has a PCIe 2.0 x16 slot and I am presently using an EVGA GeForce GTX 460 1GB. I do not run multiple displays or SLI at all. I'm considering purchasing an EVGA GeForce GTX 660Ti 2GB (http://www.newegg.com/Product/Product.aspx?Item=N82E16814130809), which is a PCIe 3.0 card.
From my own limited online research of a few hardware forums, this card will function in my PCIe 2.0 slot without any perceptible performance degradation. Can anyone confirm or deny this from their own setup or knowledge? If it actually works, it would be great because my next build will probably include a motherboard with a PCIe 3.0 slot and I could just transfer the card.

It should work just fine. Same as if you use a SATA 6 with a SATA 3 port. The performance always reverts to the lowest possible outcome. So in your case you won't be getting the benefits of PCI 3.0 (even though the card is 3.0) and will instead only get 2.0 support. In other words, your card is going to be performing slower than if it were in a 3.0 board. But I don't think you'd notice the difference overall.

Make sure the card is backwards compatible. If it's not you might fry it.

PCIe 3.0 is backwards compatible both ways. While you wouldn't get the full bandwidth of PCIe 3.0, It doesn't matter because current gen cards don't even saturate 2.0. Also, there is no risk of causing damage to the card or anything along those lines.

Thanks for the replies guys! One last thing ... am I correct in assuming that the 660Ti would be a decent upgrade from the 460?

You might not notice a huge difference in flight sim, but for gaming it is a much better card.
