Man, you guys are hammering down on him. lol But unfortunately, it's 100% true. And one thing i will say is that, you should never follow the brands, but the performance. Why does it matter if it's from ATI or Nvidia, if it performs up to your liking who gives a damn. Sadly i do believe you have wasted money, if you really want to go Nvidia now and want to have near or more performance then ATI's 5850 or 5870 you're gonna have to drop some cash on either a GTX 470/480(which are both great cards, i love my 470), otherwise you could always get a GTX 465, but from what i have read it performs in between a 5830 and 5850, so you lose some performance, but it's cheap. If not the 465, then your in a world of hurt, as anything mainstream to be released by Nvidia will not perform even close to the higher end cards from either side. So really, if your intent was to downgrade, you made a great choice, but if you have a nice amount of cash to spend on a GPU, your options are vast, from the GTX 480 to the 5970, you'll see a nice jump in performance. And if you don't have the cash... you screwed yourself over.
