It seems I need a i7 920 oc'ed to 4.1Ghz and dual 4870's to game at 1920*1200, at max settings these days. (eye-roll) But its really fact. and even then, you aren't gonna hit 60fps minimum constant.
60 frames per second
minimum? What?! Do consoles get 60 frames per second minimum? No. Average? No. In fact, current consoles often can't even maintain 30 frames per second (Just Cause 2 PS3, Madden, etc). . . Your argument about how a console is 5 years old and can play games without upgrading doesn't make
any sense because you are comparing console graphics to PC graphics.
The bad thing about PC gaming, is you can never just game. Always a newer better. I've had my 360 and Wii now for 5+ years. No upgrades there. Just games
The Wii?
Any B+ rated 5-year old PC game looks better than any Wii game ever made! Is there any game on Xbox360 that looks as good as Crysis? No. Crysis is a 3 year old game!
Did you try playing Call of Duty Modern Warfare 1 or 2 on the 360 vs. PC? What about Dragon Age Origins? Dirt 2? How can you compare graphics of 30fps at 1280x720 (or lower) on 360 to 1920x1200 on a PC? The textures on consoles are just washed out and the frames are slow to boot. Not to mention a lot of modern xbox360 games are actually running at just 1024x600.
So why is it ok to play a Wii game with horrible graphics at 30 frames per second but for a PC you expect a $150 graphics card and a $70 CPU to play a game at 60 frames at 1920x1200 + AA?

Your expectations are just unrealistic. Your PC monitor's resolution is 2.5-3.75 times what the consoles can produce. Plus you want 60 frames minimum, not just average, which is 2-3 x more frames than a console. So you are asking a $150 graphics card and a $70 cpu to be
5-10x faster than your Xbox360......how does that make any sense?
For 1920x1200, 5850 is the
bare minimum + 3.0ghz+ quad core if you want 4AA in current gen games. I am sure if you lower resolution to 1024x768 with 0AA, a PC game will still look better than the console and give you the 30 frames that you get on a console. In fact, every single console port will look better on a PC at 1024x768 4AA than on PS3 or Xbox360; and 5770 can easily do 1024x768 with any game.
