Looking to update Graphics Card, Concerned about Cooling/Power Supply

I've got a Dell XPS 8500, but I really want to upgrade the graphics card because the GT 640 is just not good enough for a lot of upcoming games. I'm looking at either a GTX 690 or GTX 680, depending on how my budget turns out. However, I'm worried that this will stretch the 460W power supply thin, or that the heat will be too much (the case is fairly liberal on fans). Can this system handle such an upgrade? Or will it be better or more cost efficient to just build a new system?

Sorry if some of the information provided is sufficient, I'm (very) new at this. Thanks for any help!

  1. I just put a GTX 650 in my 5 year old computer, upgrade from an 8600. What a difference in quality and load speeds! The 650 only requires 350 watts of stable power, I'm running it from a 600W rosewill that I got for 60$ and it hasn't had any problems.

    These new cards come with some nice heatsinks and some high RPM fans on them, so as long as your computer case isn't covered in built up hair and debris, you should be fine for temp.

    This EVGA GTX 680 beast of a GPU is hungry for 550 watts of stable power, and with a price tag of $499, I would personally wait for a few months or so for new tech, until the price drops.

    My 650 GTX was only $139, and it plays games on High settings with ~60 fps. I'm waiting for my hard drive to be fixed before I try SC2 on it.

    Hi - almost certainly building a new sys is preferable. However, the gpu's you
    are considering as well as an upgraded psu can travel to a new sys when
    you are ready to build it. In the meantime you should upgrade your gpu & PSU
    so you can start enjoying the increased perf right away. A quality 550w with(2 6pin
    connectors) PSU is sufficient for a sys with a gtx680, and a quality 620w(with 2 8pin connectors)
    is recommended for a sys with a gtx690.

    Stick with quality brands for the PSU;
    Seasonic, XFX, PC Power & Cooling, Antec, Silverstone,
    Rosewill Capstone/Fortress series, most Corsair's, most Enermax, several OCZ.

    Some to consider:

  3. Thanks very much for the rapid response! I do plan on building my own system when I get the cash together, but right now I just wanted to see if it was feasible to upgrade my current system to serve as a stop-gap in the mean time, I'm glad to see that this is possible. Especially thank you, toyftw, for the PSU recommendations. That will be very helpful.
