If the upgrade interval is too short then even hardware addicts like myself are going to have the sense to stop and say "what a minute - I just upgraded - can I really afford to spend $800 a year on video cards?...".
I don't know much about PCI-Express but the boards and the cards are already here, aren't they - at least the 600xt? That's a completely different interface on the card, right? (You have to have a new motherboard to run PCI-Express cards, correct?).
Doesn't this HardOCP Doom 3 benchmarks article showing the PCI-Express card clearly outperforming their AGP counterparts make you a little nervous about upgrading to the AGP version? Am I missing something here, or do the PCI-Express cards significantly outperform the AGP versions?
No you have it backwards lol. They aren'y releasing PCIe boards yet because not enough people have broken down and bought AGP cards yet! Only when everyone and their grandmother has a AGP version will the PCIe versions be released... sorta like Intels business practice before AMD had any real competition in performance. Ie: "Even though we have 300 Mhz chips, lets wait till everyone buys the 200 Mhz version then release a 201 Mhz version!". Make everybody buy two of the same card... ah yes, I think its called 'milking'
The PCIe version of the benchmark is also using a 3.6 Ghz CPU and the AGP version is 3.2 Ghz, that is probably enough to account for the difference. PCIe isnt really going to be any 'better' than AGP at the moment, its more the fact that PCIe is the biggest thing for PCs since the original PCI replaced ISA and the VLB hack (AGP = another type of VLB hack). A point to point packet switched serial bus seems to be the way to the future. Reguardless of better performance, if the PCIe stuff is around the corner, why bother with AGP? But I guess it doesnt matter; at this rate there will be 6 generations of mainboards and CPUs out before we see a PCIe card worth talking about that isn't an elitist 'reviewers only' board.
Framebuffer reads have always been a bad thing due to the 1 way nature of AGP and slow PCI bus speeds in general. With PCIe supporting 4gb/s bidirectional, it will be interesting to see some new framebuffer post processing techniques or hybrid CPU/GPU effects assuming very fast GPUs and GDDR3 memory don't stall the CPU for the lock.
