I see that a single 5670 made it into the best graphics cards for the money in April, but in the two hundred dollar range Tom's suggestion was a pair of 4850's. Now for the same price a can have a setup with two 5670's. Unless I'm missing something this seems to be the better route to go as the 5670 has DX11 support.
Is there something I'm missing? not an expert with graphics cards, but I'm looking for a card that will last me a while and still packs a punch. Thanks!
The 5670 is significantly weaker than the 4850. The 5750 performs near 4850 levels. The 5670 has half as many stream processors as the 4850. DX11 support is not very important, especially considering a 5670 would choke playing DX11 games.
BTW, what resolution are you playing at and what games?
It will not perform better. But, it will take less power, support dx11, and eyefinity. And, judging from Tom's graphs, it will handle L4D2 at that resolution with 4xAA no problem. But if you want to play other, more demanding games, and still max them with AA, the 4850s are the way to go.
