pcie 4x vs. 16x

[movingincircles]

does 16x improve graphics performance over the 4x slots?


how about pcie 16x vs. 8x agp

or pcie 4x vs. 8x agp (supposedly agp has more bandwith in this one)

A PCI-E card needs a 16x slot(provided its not a crazy PCI-E 1x gfx card)

Well, thats a bit of a weird question. The problem is, graphics cards and 4X slots are really synonymous, I can't think of any video card that comes in a 4x port nor a mobo with a 4x port.

PCIe 16X or 32X or even 8X isn't even necessary unless of course you were running your video memory off of the system bus, which would be severely performance hindered and not worth it at all. Using system memory and video ram is a good way to kill graphics performance, if you get a card that does not suffer this issue, than the system bus is non-issue past AGP 2X equivalent speed. Basically stick with what ever is cheaper or available, even PCIe 1x slots aren't nearly as bad as the original PCI slots.

the asrock 775DUAL-VSTA mobo has a 4x pcie

so i should stick with AGP for now since it's cheaper?

I'm wondering this as well. Their are x16 slots with x4 connections. Theoretically they have enough bandwidth , but does anyone have benchies?

AGP is most certainly not cheaper from the mid to high end. It's only cheaper if you're keeping the GPU from your old system.
