The AMD 6850 is a very good performer at a decent price. Link

You need to REALLY be careful about judging power supplies based solely on wattage ratings. There are roughly 8 bajillion terrible 1000 watt PSUs made by shady manufacturers on the market that you want to stay very far away from. You need to look for good brands like Antec, Seasonic and Corsair. This Corsair PSU will definitely be enough for you. Here's a cheaper Antec PSU that should also be just fine.
Note that if you aren't going to be gaming at high resolutions (1920x1080 +), you can really scale back a lot on the video card and PSU department. That AMD 6450 might be enough.
If I was in your shoes I'd buy that Dell XPS 8300 and try it out with the monitor you have. Crank up the graphics options on your favourite game to maximum and see how it goes. That computer absolutely won't be limited by CPU or RAM - the bottleneck will definitely be all in the video card. If things are choppy or slower than you'd like, you have a nice upgrade path in the video card and PSU departments.
