That money could be spent somewhere else. For example, you could replace your GTS 450 for something more powerful; use it for PhysX and you would get more PPD. (GTX 460 would be a good place to start).
You could get a custom-loop, put your 590 underwater, grab a new stereo system. Migrate to a new desk. Get two more monitors for Surround (a single GTX 590 will be able to handle most games with decent settings, but will be VRAM limited; no way around this with your current setup. Heck, you could even get an i7 970 and give your rig another leg up on future applications
Two 590s on a single 1200p is NOT useless.
I use every bit of my Tri-Fire 6970 setup on only 1080p.
I like cranking up at least 8x MSAA and Ultra everything. On a 120hz monitor, which SHOULD be the norm soon with alot of OC.net'izens, you can VERY well make use of that extra horsepower. With Tri-fire 6970s I'm just barely able to make use of the 120hz monitor maxed out with just 4x MSAA. I average about 100fps which is PERFECT for a multiplayer FPS scenario. If you haven't FELT the difference, you wont think it's a big deal. But going from 60fps to 120fps ON a 120hz monitor, IS a big deal. Even with vsync off on a 60hz you'll notice it, because having a 60fps MINIMUM is ideal. A 60fps average isnt ***** if you can't keep your minimums above 30 during firefights, when you NEED responsiveness. When I'm in big firefights I like having that twitch response and I play 2x better and I'm WAY more immersed in the experience.
In my opinion, ANY sort of slowdown detracts from the overall experience, and in a game you want every little advantage you can get as far as immersion goes.
Is it necessary? No. Could I play BF3 on my 5870 and be happy? Yes, I have for the first few days it was out, while awaiting my shipments. I had to run on High with High PostAA, 1080p, and no AA. It was responsive, with a 55fps average with a minimum in the low 40s. It was playable, and more than enough for the casual gamer, but not for me.
I'll tell you this, once you taste that extra horsepower you'll never be satisfied with less. There will always be the 'What If' situations when you're on lesser hardware.
Good luck. As far as the 590, you could just OC it and spend the $ on a water block and increase your performance another 15-20%, which is noticeable, and at the same time improve the experience for FAR less $, and quite possibly give you just enough more performance to be playable in an Nvidia Surround setup or in that 3D game that is dropping to 30fps Vsync because the average is below 60 for example.
