The article suggests the GTS 250 isn't significantly worse than the 9800 GTX. I'd suggest sticking with the GTS 250 or going with a Radeon 4850, or if you can afford a little more, step up to a Radeon 5750.
The 9800 GTX+ and GTS 250 are basically the same spec and perform almost identically. The GTS 250 is newer manufacturing and uses less power/generates less heat. If they are about the same price, choose the GTS 250. At the near $100 US price point the 250 and the 4850 are the best deals.
If you can bump up the budget a bit the ati 5770 is around 50% faster and gives you DX11, making it a better price/performance value.
In a 3.2Gz dual core system the 5770 will play crysis smoothly at medium settings and 1920x1080 resolution. Crysis at medium looks as good as most games at DX10 ultra high. You should be fairly happy with it.
