GeForce 640 upgrade to 560 ti?

I bought an alienware x51 about 8 months ago with the i5 3330 cpu and the gtx 640 gpu and so far the 640 hasnt given me the results i had hoped for and i was wondering if it would make sense to swap it out for the gtx 560 or the gtx 560 ti given that those cards are around $100

PS: im no expert but i think that the 560 would require more than the current 330w power supply that comes with the x51

  1. The regular 560 should run on that power supply. The Ti would be a bit close to max power usage all the time, I would not get that without a new power supply.

    how about the radeon 7770? if so is that a worthy upgrade?
  3. The 640 is a low end gaming card, lower than the lowest recommended one on Toms. Look at the reiew here http://www.tomshardware.com/reviews/geforce-gt-640-review,3214-7.html

    It looks like even a Radeon 7750 which is pretty low power can outrun that 640 by quite a bit. A 7770 will be a good pick and the power use for review systems is 30-40 watts less than for a 560.

    The issue is that the case of the X51 is pretty small, make sure the cards will fit.
  4. will i need to upgrade my power supply if i go with the 7770? also whats up with the x51's power brick or laptop charger thing or whatever that is, is that normal for a desktop and how does that factor in to all this? sorry if im asking dumb questions but i need some things clarified

    The 7770 should run on your power supply, I don't see Alienware brand even it's Dell now having a poor quality PSU. Just make sure you have enough space in the case to fit the card. With how small the case is, you may be stuck with a 7750 due to size and heat issues. I don't know about the powersupply on that model, but if it's an external one, no it's not normal for a desktop at all, but should not matter as long as you have power cables to run the card.

    The other option they have listed for the computer is NVIDIA® GeForce® GTX 660 1.5GB GDDR5

    If that card can run in the system, a 7770 should as well.
