RE: Cisco G2 ISR WAN performance of 1Gbps?

Experts,

I have got one question if anyone could clarify please.

Are the new G2 ISRs 29xx & 39xx capable of handling 1Gbps WAN throughput using HWIC-1GE-SFP, as 28xx/38xx had limitation *** (see below) of max 500Mbps due to HWIC interface bus speed limitation ?

G2 supports EHWICs; What are the new EHWICs available? Is there any EHWICs for 1Gbps?

What is the best (lowest cost) Cisco router that can support 1Gbps Ethernet WAN? Do I need ASR for this? I need three 1Gbps interfaces.

Q. Q: What is the maximum throughput on the Gigabit Ethernet HWIC?
A: A: The HWIC bus interface is limited to 400 Mbps of full duplex. The actual throughput of the Gigabit Ethernet HWIC is limited by the throughput of individual platforms. Under bidirectional traffic of 1518 bytes or larger, the Gigabit Ethernet HWIC can support up to an aggregate of 350 Mbps on Cisco 2811 and 2821 routers, 400 Mbps on Cisco 2851 routers, and 500 Mbps on Cisco 3800 Series platforms.
