I agree, there is no performance gain right now for PCIe. However, you are looking at this only from one angle. It's not about the performance, it's about the platform, and a PCIe S939 system is a good platform that will last for a pretty long time, probably something like Socket A. Sure, right now, PCIe supply is rather short, but nVidia and ATI have been changing that with their latest releases, and fully intend to focus on PCIe from now on, while AGP will be taking a back seat. Computer sellers like Dell and Gateway are also encouraging this, since most of their new systems, even ones with integrated video, have PCIe, so there will be a big market base pretty soon, without consumers even knowing it. In a year or 2, when you want to upgrade, you'll be able to get a pretty nice upgrade for your CPU, (imagine going from a 3000+ to a 4400+, or even a dual core), but if you have an AGP system, your selections will look much like PCI selections now. It's just not a good situation. Plus, by the time you upgrade, graphics cards will be optimized to take advantage of PCIe's advanced upstream bandwidth, enabling larger, less used textures to be stored in main memory, and fetched without too much delay, so cards will run faster on PCIe eventually, much like AGP cards eventually became much faster than PCI ones. Also, SLI, if that's your thing, does provide a nice upgrade path, or disgusting performance now, depending on how you use it. The other main advantage of PCIe is not for graphics, but for peripherals. PCI is too damn slow - you have 133MB/s bandwidth TOTAL, which can easily be saturated by just a simple SATA controller. PCIe has almost double that FOR EACH lane, meaning you can have several high speed peripherals on your system later down the road, like HD Sound cards, 10GB Ethernet, 802.11n and higher wireless, HD Video capture, future specifications of USB and firewire, etc. These will all be impossible on handle on PCI, so you will miss out on a whole generation of peripherals.
Other than PCIe, there are several other features of next-gen chipsets that are worthwhile. nForce4 Ultra and SLI support SATA-II, which will allow for faster hard drives, and can handle current NCQ hard drives for a bit of a speed boost. They also have a hardware firewall/gigabit ethernet combo that allows for high speeds while moving the CPU load off to the chipset hardware, speeding up your system. The K8T890 Pro lacks these things, but does have HD-Audio built in, and has an NCQ SATA-1 controller.
