I'm trying to upgrade my video card on my somewhat old, but still powerful, motherboard. I'm not in the market for a full system upgrade so I'm not going to replace the mobo, not for a while. All I'm looking to do is maximize the performance of the system I have.
My question revolves around card performance when limited by the PCI bus speed. My mobo has PCIe x16, and I'm contemplating upgrading to a PCIe 2.0 card. I'm debating several cards, trying to balance cost and performance.
I know the 2.0 cards are perfectly backwards compatible to my mobo, but how much of a performance hit should I expect? Looking at detailed specs [http://www.hardwaresecrets.com/article/132] I know that the 2.0 cards I want have more than double the memory transfer rate of the 1.0 card I want, but what I can't figure out is if those numbers will be halved by my 1.0 bus.
Specifically I'm debating between an 8600 GTS [the 1.0 card I like], several 9600s and a couple 9800s. The 9 series cards range from 1.8 to 2.2 times the transfer rate of the 8600. According to the above table, the specs provided for the 9 series cards are based on 2.0 bus, which I obviously don't have. Should I expect, for example, a 9800 GTX to only use half it's potential because of the bus, or is the performance cut going to be small?
I guess the simplest way to word my question is this: Is my mobo going to limit a 96 or 9800 card so much that I won't see much better performance, and therefore the 8600 is a better buy?
