Hi, I am thinking of upgrading my above setup to a single card. I seem always to have used ATI/AMD cards and looking at the various reviews I feel that a change to a Nvidia GTX 4** card might be the way to go. I would like a card that will out perform the twin 5700's I have now with a view to perhaps doubling them up later. A budget of around the £200 mark is what I have. There is no rush for this upgrade, so if there is a chance of a price reduction that I should wait for in the relative near future, that is not a problem. I have listed current specs in case there is a need to upgrade the PSU along with the card. I am also a bit of a gamer hence the need always to upgrade.Sad I know. Thanks.
