I recommend a 6790. I picked mine up a couple weeks ago for $89 and this thing kicks some serious butt/$. 6 months ago these cards did not make sense when they were priced within $10 of a 6850, but now they cost half of one of those, and two 6790s crossfired perform neck and neck with two 6850s. The 6790 is actually a 6800 series BARTs GPU with a 256 bit memory interface, and are known to scale above 90% when Crossfired compared to ~80% for most 6000 series cards. I am going to be getting another one of these in the near future myself, which will yield somewhere in the performance range of a (single) 6970 for half the price. Having a 6790 and a 6970 in the same series is about the worst naming regiment I have ever seen.
They should have called these cards something like a 6830 instead of giving them a 6700 series moniker.Here is a good breakdown of what the 6790 can do
, especially in Crossfire.
