PCI Express
on Feb 15, 2009 at 11:42:27 pm

building a i7 based pc.
I have been looking at motherboards but have no idea what layouts would advantage a video and music editing PC in terms of:

PCI Express x16, x8, x4, and x1 slots,

when I last built a pc it was just PCI.

Motherboards available from system builders in my area all have different configurations of slots sata esata usb firewire.

P6T Deluxe
3 x PCIe 2.0 x16 (at x16/x16/x1 or x16/x8/x8 mode)
1 x PCIe x4
2 x PCI
2 IEEE 1394
6 x SATA connectors
2 x SAS connectors
1 x eSATA
14 USB 2.0 ports

Gigabyte GA-EX58-UD5
2 x PCI Express x16 slots, running at x16 PCIEX16_1/PCIEX16_2)
1 x PCI Express x8 slot, running at x8 (PCIEX8_1)
1 x PCI Express x4 slot
1 x PCI Express x1 slot
2 x PCI slots
10 x SATA
12 x USB
3 x 1394
12 x USB

• 2 PCI Express gen2 x16 slots -
• 3 PCI Express gen2 x1 slots
• 2 PCI slot, support 3.3V/ 5V PCI bus Interface
2 IEEE 1394
8 x SATA,
1 x eSATA
10 x USB

MSI X58 Eclipse
3 PCI Express gen2 x16 slots
• two PCIE x16 slots (PCI_E2 &PCI_E4) support up to PCIE x16 speed,
• one PCIE x16 slot(PCI_ E5) supports up to PCIE x4 speed
• 2 PCI Express x1 slots
• 2 PCI slot, support 3.3V/ 5V PCI bus Interface
10 x SATA
2 x eSATA ports
2 x IEEE1394 port
10 x USB

What slots do NLE hardware and Audio hardware use these days ?
or should I not worry about this and choose the one with the best sata and firewire?

not sure if I fully understand what you're wanting to know.
they're are mutltiple PCI express ports because of gamers wanting to put two or three high end video cards into their computer so they can have 2-3 monitors while playing their game.
don't worry about how many pci express ports for video cards.

what type of slot(s) do you need for your NLE hardware.. then make sure the MOBO, you pick, has an open (free and clear from the video card's profile) slot for that card.

sorry for sounding harsh but

if you have to ask this you should not be building a computer for NLE

PCI is going away, PCIe is the replacement.

PCIe cards such as AJA, Decklink etc as well as newer firewire cards.

something I am considering is expandability
The graphics cards I am considering cover 2 slots because of large cooling fans

Gigabyte GA-EX58-UD5 you loose a pci slot
Asus P6T Deluxe you loose a pci slot
MSI Eclipse you lose the only spare PCie x1 slot
MSI X58 PLATINUM you lose a pcie x1 slot of three total

I found this on wikipedia
" a PCIe card will physically fit (and work correctly) in any slot that is at least as large as it is (e.g. an x1 sized card will work in any sized slot); "

I didnt know you could install pcie i/o cards in a graphics slot
I guess not many manufacturers will releasing be 64 bit drivers for pci cards

Nope, just Nvidia, ATI, Matrox, Canopus, Black Magic, Creative Labs... Of course there are 64 bit dirvers!

It seems you haven't configured a system since the AGP era! The same way AGP got obsolete, the PCI slot has gotten obsolete too. PCIe is the next I/O stadard. In fact, asus has a workstation board with 6 PCIe.

Before choosing a mobo, choose yor NLE app and hardware and build the system based on that. I'm sure you can find help in this forum, but first let us know what will you be using for editing, is DV only or you want to work with HDV, are you an after effect user? are u on a budget? or a hobbist and want to play with movie maker?
