Unless your cables are really bad, or really long, I doubt they will be a problem.
The switches you use, the cards you use, and the boards you use are generally the bottlenecks, I find.
You can use iperf to test a network's bandwidth.

GSIP(4) BSD Kernel Interfaces Manual GSIP(4)
NAME
gsip -- National Semiconductor DP83820 Gigabit Ethernet driver
SYNOPSIS
gsip* at pci? dev ? function ?
Configuration of PHYs may also be necessary. See mii(4).
DESCRIPTION
The gsip device driver supports Gigabit Ethernet interfaces based on the National Semiconductor DP83820 Gigabit Ethernet chips.
The National Semiconductor DP83820 is found on NetGear GA-622, Asante FriendlyNet GigaNIX, D-Link DGE-500T, SMC 9452TX and 9462TX, Accton
EN1407-T, Planex GN-1000TE, ARK SOHO GA2000T and GA2500T, and other low-cost Gigabit Ethernet cards. It uses an external PHY or an external
10-bit interface.
The DP83820 supports VLAN tag insertion/removal in hardware. The gsip driver supports this feature of the chip.
The DP83820 supports IPv4/TCP/UDP checksumming in hardware. The gsip driver supports this feature of the chip. See ifconfig(8) for informa-
tion on how to enable this feature.
The DP83820 chip is a close relative of the DP83815 10/100 Ethernet chip, which is supported by the sip(4) driver, hence the gsip name.
SEE ALSO
arp(4), ifmedia(4), mii(4), netintro(4), pci(4), vlan(4), ifconfig(8)
HISTORY
The gsip driver first appeared in NetBSD 1.6.
AUTHORS
The gsip driver was written by Jason R. Thorpe <thorpej@NetBSD.org>.
BUGS
The gsip driver does not support the 10-bit interface, which is required in order to support fiber-optic media.
