the 9600GT is a good mid range card for a lower resolution, it wont max all games but there is far worse out there to game with, i would just go for the 512mb model though, the 1gb model is a bit of a gimmick & cannot properly utilize the extra 512mb on a 256bit interface
2 of these in SLI deliver great performance at a low price
as for POV.....you'll probably get 3 years warranty, but basically the cheaper cards are usually built with the more marginal chips off of a wafer (same with the memory on them), the process is known as chip binning and it's industry wide practice, better chips go into more expensive products.
that's not saying POV are no good, but you get what you pay for.
