Suggestions on Video Card(S)

Your budget? resolution?

Your range should be around gtx 260/275 ati 4870/4890

I believe your board supports cf, correct me if im wrong.
Go with 4890 they will perform amazing in your rig and are very affordable now after rebate.

If its this board http://www.newegg.com/Product/Prod [...] 6813131363
it will support up to 4 ati cards. Yes it will work with 2 4890's.

Get the 4890.
Good choice on the MB, too, it's one of the few where dual card slots are placed a sensible distance apart!
You might want to reconsider the PSU, though. Apevia are not known as a top quality builder.
If you plan on CF later, or even now, I' siggest 700-800W from OCZ, Antec, Corsair, Pc Power and Cooling or Silverstone, but check the one you select has the correct number of PCI-E connectors. For a single card, you'll need no more than 500-550W from any of those manufacturers, onve again, provided it has enough PCI-E connectors.

@ Nvv: The PSU you linked to has only 2 PCI-E connectors, not enough for Crossfire and its output (and cost) are excessive for a single card configuration.
Adaptors exist allowing you to draw power from Molex connectors, but it is not a good idea, particularly with a card that draws as much power as a HD4890.

Most of the cards of the type you have linked to (reference cooler) are much the same If you like HIS, then get it, nobody else is making them any better

For a single card this is nice:
