Am I right in thinking a gigabit card is a gigabit card and theres no point going for say a £20 one compared to a £5 one?
 
Kindof . . . .

Sometimes the more expensive cards have their own processing on the card, some have better features (WOL etc) some are just plain better.

I wholly recommend the Intel PRO/1000 cards. I use them and they are excellent. Get the PCI-E ones of course!
 
Any ideas on the quality of these? "Tenda Gigabit Network Interface Card". They have good reviews and are only £5.49
 
PCI one will be fine, but if you have the space and the slots why not get a PCI-e one.

You would need to be doing some crazy things to saturate a PCI bus with a gigabit card.

PCI will allow for 133MB a sec as a theoretical max. A gigabit card, what 110MB a sec or so, and the PCI bus is shared, so any other devices will contend. If it gets to the point where that is limiting you, then you have other issues and should take a closer look at what you are doing.

266MB/s, this isnt 1994 ^^ a gigabit nic will work fine via PCI
 
I've got a Broadcom netXtreme in my server, which I get good speeds over (~800Mb/s throughput)

Vista and Win7 have a dynamic TCP window sizing tech, which can make a massive difference. Without it you generally won't see more than around 350Mb/s throughput.

I thought a PCI bus was 32bit / 33Mhz which works out at 133MB

checking wiki
The PCI specification also provides options for 3.3 V signaling, 64-bit bus width, and 66 MHz clocking, but these are not commonly encountered outside of PCI-X support on server motherboards.

I'm certainly aware of 64bit / PCI-X but is wiki wrong and general non server boards support 66Mhz 32bit PCI? Which ones? (Or is it only via overclocking ? )


Looking at this page -http://www.compute-aid.com/64bitpci.html

theres and interesting quot at the bottom - can anyonfe find the source or the 'test'?
Intel conducted a test in 1999 for the Gigabit ethernet. Their test result shows the full Gigabit bandwidth can only be achieved by implementing the 66MHz 64bit PCI bus, as well as use CPU and memory that fast enough not causing bottleneck effect. We have conducted the test in Compute Aid, Inc.'s lab for the Intel Gigabit ethernet card and switch (based on chips made by HP), they work flawlessly.

Any idea what Edimax EN-9260TX-E PCIe cards are like for around £10?

Also whats the difference between the two models (EN-9250TX-E & EN-9260TX-E) apart from looks?

Not been following home networking for a while. Is cat5 fine for gigabit ethernet?

yes, Cat5e supports gigabit ethernet over the full length. You only need better cable (such as cat6a) if you want to future proof for 10gigabit ethernet (LONG way from reaching the home market).
