Nice. EVGA is a good brand-and those are virtually the same card. (the 250 is just the 2009 rebranding attempt) Nvidia cards are still using gddr3 too--so if the above gddr5 thing is actually true (i dont know) it might be smart.
Still, i should note that competitive in this price range are any inventories of ($89)4850s or ($135)4870s that haven't been cleared out yet. It appears that newegg's inventory has been mostly updated to the 57xx cards but some other retailers might still have them at that price. The 4850 is very close to the power of the cards you listed, and the 4870 is more powerful. (also the 4770 is competitive to a gts 250, but i dont know how much of its power relies on the gddr5)
