I'm having a hard time finding information about how to pick a GPU to run hi-res (maybe 2600x1440) on a 27 inch monitor. Also, might get another monitor in the future so I know the card needs dual link DVI. What about ram and other stuff? Could a 1gb 7850 (http://www.newegg.com/Product/Product.a ... 6814150642) fit or would 2gb cards be required?

It depends on what you're going to do. If you're not going to play games, then pretty much any GPU will do as long as it supports the resolution. As for that resolution though, you need at least a dual-link DVI cable or DisplayPort cable. I honestly prefer DisplayPort because dual-link DVI cables are thick and kind of hard to route. Otherwise memory doesn't really matter since most of them are sufficient anyway.

If you're going to play games then you're going to need a really beefy GPU to obtain playable framerates at high settings.

There's no gaming on this but HD videos though. It lags with an AMD 5450 passive card at that high res for 1080p videos. It only has the 24 pin DVI-D port so displayport is not an option.

If I read correctly on other reviews, the GPUs with the dual DVI link have one DVI-D and one DVI-I. I think the second monitor just plugs into the DVI-I port.

I'm seeing AMD 7850s going on sale for $100 now. Can I expect something similar from Nvidia options too? The GTX650ti is similar to the 7850, right?

The GTX 650 Ti should be more than enough. However I'm more concerned about the claim that 1080p videos lag on the 5450, because 1080p is practically a joke to render even on low-end processors these days (if comparatively weak cellphone can do 1080p just fine, then something else is wrong here).
