Just recently bought an EVGA GTS 250 from TigerDirect. It doesn't get reconized when I start windows and I don't think it's working at all because it stays really cold. I also noticed that it doesn't snap into place on the slot, but I don't think that's the problem because I'm pretty sure that I pushed it in as far as it will go. I know it's not the slot itself because my old graphics card still works great. I'm thinking it's my PSU, but it's 500W so I still doubt it but I have no other ideas.
The new 470 that drops on march 26 will reportedly sell for $349 ....and is reportedly 5-10% faster than the 5850 now selling for $340. We could argue all day about the merits of each based upon supposition but in a week, it won't be a guess anymore.....I say wait a week before deciding which way to go.
