It's fine to get the i5 3570 based on price, but if you do that, you should grab a 3470 or 3450. VT-d is only for remapping raw PCIe devices, which you pretty much never do in a desktop environment (it's not like you have extra GPUs, NICs, or SAS cards sitting in the machine).

I thought it also had performance gains for running any virtualized systems?

Nope, it does not. All it does is virtualize the IOMMU so that you can remap PCIe devices directly to the VMs.

I/O MMU virtualization (AMD-Vi and VT-d)

Main article: IOMMU
An input/output memory management unit (IOMMU) enables guest virtual machines to directly use peripheral devices, such as Ethernet, accelerated graphics cards, and hard-drive controllers, through DMA and interrupt remapping. This is sometimes called PCI passthrough.[31] Both AMD and Intel have released specifications:

• AMD's I/O Virtualization Technology, "AMD-Vi", originally called "IOMMU".[32]
• Intel's "Virtualization Technology for Directed I/O" (VT-d).[33] Included in most but not all Nehalem based processors.[34]

Hmm, not sure if I'd really have any use for that then. Although being able to play a game in the virtual pc sounds like a cool but totally useless thing to do

 

[mfenn]

Well, you'd need an entirely separate GPU and monitor to do that. So yeah, pretty useless. :awe:
