ADDITIONAL COMMENTS: I had in mind of the HP Pavilion Elite e9210t or using PCMag's AMD Gaming System build-up before posting this. However I want to know if there is a better build that the community can suggest for the best use of $850. I'm fine with AMD preference like that PCmag build up. Saving few bucks couldn't be THAT bad, right?
Those builds aren't going to fly at that resolution. You need to build around a Radeon 5850 to get strong gaming results at that resolution, which means backorder. If you need a $170 1900x1080 monitor too, you're going to end up fairly unhappy with what you can buy for $900. This is the best box I can put together to run a 1900x1080 for $900:
Total cost: $882, + ~$10 shipping, + sales tax if applicable
That's as tight as I can make it, working every good deal I know on good components from a recent build.
If you need to skimp further, I don't know what to tell you. Either you want to buy a monitor with less resolution and buy a cheaper video card, or you want to buy a lesser video card now, turn the eye candy down for the moment and upgrade the video card later.
But that's just penny wise and pound foolish. You'd be better off getting the GPU that'll power your hardware well now and carrying a balance of $100 for several years on a credit card at 30% interest than you would be upgrading the card. If you can scrape together the extra $100-$150 above your budget, you should.
Other options: you could lose the inexpensive cooler and run stock. You could throttle down to a Phenom III to save $50 or so. You could scale back the RAM speed a bit to save $20 or so. All of those choices are going to bottleneck you, and you'll fall into the same upgrade trap.
In short, borrow to extend your budget if you're set on 1900x1080 and you don't own the monitor already. If you're not set on 1900x1080 and borrowing isn't an option, buy a cheaper video card and go 1680x1050 instead.
