Hey, I have a Pavilion Slimline to (s3431.uk though), shame about warcraft though that game makes people addicted. So you are interested in upgrading your card, tell me what card you have now? I upgraded my graphics card to, i'll tell you about it. I had a ATI Radeon 3450 is that what you have now? I went to pcupgrade and asked what was the best graphics card for my computer that would work on 160watts. They recommened the ATI Radeon 4550 and that it was the best possible card to work on my computer. The card manufacturer says that it should be powered by a PSU of 300watts minimum. But pcupgrade told me that the card will work on computers with PSU's as low as 150 watts. This is because they say of the 45nm wafer thin technology, the card only consumes up to 25 watts on full power. The performance should be boosted up slightly have a look at the performance on the charts over here. I suppose it is worth it, such as i play FarCry, before when i had the ATI 3450 i couldn't play it more than minimum settings because of the poor FPS I got out of the game, but now i can play the settings on ultra high. The game has a minimum requirement of 64mb of graphics and i would suggest to sticking to games which require that amount of graphics minimum if you want to get adequate performance out of the card. If you are interested in buying the card i bought mine from play.com for £45. I think the cheapest there is to buy is available on play.com. Please reply to me if you have any more questions. And also to let you know the card is low profile to and is packaged with a low profile bracket, so don't worry about that.
