What kind of power supply do I need to do this? I want this card exactly I already know about the 9800GT obliterating this card and being better. How many watts do I need and what brand besides a $70+ corsair can give me this?

  1. Your current power supply should handle that card but this card;
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814102870
    is significantly faster, DX11 compatible, supports 3 monitors, has more current A/V playback features, costs less and wont take "7-21 days" to ship.

    Are you sure EVEN with my Quad Core and 8 gigs ram?

    Yeah, I'm sure. Dell uses good power supplies and rates them for continuous usage rather than peak like a lot of other brands.
    The max TDP of the Q8200 is 95w while both of the cards we are discussing use less than 60w of power. The rest of your system likely draws less than 50w max. A few times on here people have reported using HD5750s on 300w Dell PSUs even.

    Is it safe to test these cards on PSU? as in any risks in case I have a cruddy PSU? also can the 512mb do 1080p well?
  5. If the PSU isn't good enough usually the system simply will not start up or it will restart itself when you go to play a game. But seriously, the numbers I gave you are correct, you can look them up.
    As for 1080p the class of cards you are looking at aren't really appropriate for gaming at that resolution no matter how much memory they have. If you really can't spend more then definitely get the HD5670. 1gb does help at 1080p but only on cards powerful enough to use it and these cards aren't. The extra processing power on the HD5670 will certainly help much more. I just looked up the numbers and the HD5670 512mb is on average approximately 20% faster than a 1gb GT 240 at 1920x1080.
    Like I said though the card isn't really meant for 1080p. Current games will be playable but in most you'll need to turn the graphics setting down to medium or low. For that resolution I would recommend at minimum getting a decent 400w PSU and an HD5770 if you want something that will give you good performance.
