Just over a month ago I stupidly applied the wrong overclock to my current GTX 275 and now get graphic anomalies in some games when temps reach over 67 degrees. I have set-up a more aggressive fan profile in Rivatuner to keep temps down. This is an issue in both Vista and XP with different drivers so I am fairly certain I have cooked the card. I bought the card from the high street and have lost my receipt and even though its only 7 months old I will not be able to replace it.
As this is not a planned upgrade my choices have been made difficult because in the past I have usually spent £200 to £220 for a new card that gave 40 to 50% performance increase over my then current card (this is at 1680 x 1050). If I buy now I'm only going to get a 20% performance increase for £220 (HD 5850) and 40% for £320 (HD 5870) - GTX 470 will be somewhere in between.
Currently I have preference towards nVidia drivers as they have been more stable for me and there are more games where you can force AA to work than with Ati drivers. That said I am still disappointed with the new Fermi cards as they do not appear to be very good value for money. The GTX 470 competes with the 5870 yet is slower. I am not sure how a overclocked 470 will cope with my very hot study in the peak of summer.
I not even sure if the 470 will fit into a Antec 300 and I know the HD 5870 only just fits.
My choices are £220 for a HD 5850 or £320 for a HD 5870 or GTX 470. I am not sure which way to go on this one.
