Can you use a GFX card that PCI-e 3.0 in a 2.0 slot?

I'm upgrading my GFX card and I have a decent amount to spend. But the slot in my PC is 2.0 and I was going to get a 600 series Nvidia card, but they are all 3.0.

Also, whats a good place to get a GFX card at a decent price that has a good rep besides Tigerdirect or Newegg?

It will work.

For US customers, Newegg seems like the place to get parts online. I see multiple references to it time and time again

My 680 works perfectly fine in my P6T Deluxe (only 2.0 slots) - and according to the 3DMark 11 scores I got, it performs better than other computers running the same hardware (whole computer did actually /epeen)
PCI-E slots are back- and forwards compatible, so the card won't be able to perform 100%, but it's still amazingly fast.

In short; It works just fine, but you won't really notice a difference.

Newegg is the best place to research products (based purely on products specs) because of their extensive website database, and easily filterable/searchable content, this is true globally even if you can't buy from them. You can buy at whatever cheap trustworthy business you want.

actually it well perform at 100% games are not using all the available PCI-E v2 Bandwidth, there still only using around 5/8 of the available bandwidth

What he said. PCIe 3.0 is a future standard for triple and quad SLI/Crossfire setups that eventually overtake the PCIe 2.0 bandwidth capacity (this is a ways off yet). As of right now there is nothing that saturates the PCIe 2.0 bus, and a single card setup comes nowhere even close.

The PCIe standard and fully backwards compatible, so no worries there. PCIe 4.0 is already under development.
