In simple words can a 6450 (2.1 PCIE) fit in my DFI LP-UT nF4 SLI-DR?

Unless there's been a voltage change between 1.0 and 2.1, yes. Of course you'd be limited to Pcie 1.0 speeds .

I'm on a phone just now, so I'd recommend looking at the pcie wiki page and x=check that the voltages haven't changed - they did for agp at one point.

As David said, the card will work fine in a PCI-E 16x v1.0 slot.

There's no voltage differences between v1.0/2.0/2.1 that would prevent the card being used.

Then only difference between the two standards. Is that PCI-E 1.0 got lower bandwith than 2.1.
But it wont matter when it comes to gpus. Since no graphicscard can max that bandwith at the moment.
But it does matter a bit when it comes to high end raid cards.

Raid cards? You mean Sli/crossfire. And also they each get their own bandwidth so it wouldn't matter.

Well the only cards ive seen that does use more than the bandwith of PCI-E 1.0, is raid cards. Even if youre running up to 2 cards.

It's not a high-end card, so the slot difference won't matter. It's not going to max out a PCI-E 1.0 16x slot.

Hate to bump it up, but thanks for the info! I'm on an old x2 @ 2.9GHz rig and want to wait just a little before jumping on a major upgrade (six core, new graphics), and being able to switch to a much newer graphics card helps a lot!

Definitely. It'll make a huge difference depending on your monitor resolution, and you can carry it over when you upgrade your board/CPU.
