7600GT vs x1950 pro for an aging machine?

Hi,

I'm looking to extend the life of my old machine a bit longer with a video card upgrade. It's a p4 3.0, 1gig, x1300. I know, it's old, but it's "good enough" for my purposes. I don't need to run high res's or max settings, just decent quality with a decent framerate is good enough for me and I'm sure a new card can offer me that for now.

The problem is I'm unsure as to whether or not my machine can handle the x1950. This is my PSU -

I've been reading about 12v, and the requirements for the x1950, but those stats confuse me. I've never seen a "+12v, -12v" config with such high amps. Is that just a typo? And would that PSU be ok for the x1950?

I imagine the x1950 is overkill for my machine, but where I live the price difference between the 7600GT and the x1950 is neglible. Basically, the choice is between the safe, old-computer friendly 7600GT.. or the riskier, but probably noticeably superior even on my machine x1950.

Any advice greatly appreciated. Thanks.

You do have the option of going with a 1950gt its basically a under clocked 1950 pro it has the same core and i have heard that they can be overclocked ok to about pro level.
Reading the psu label i am going to assume that the second rail is a typo and should be a + which if correct gives you 28 amps accross your +12 rails which should be enough to run a pro, Given the p3 and 1 gig of ram i would go this way as you can basically customise the card to suit the machine ie fit a GT if you and the pc seem happy leave well alone if you fell you want you can oc a bit then throttle it back if you start to get probs or no real increase
Mactronix

pro would do you just fine. Your psu should also be okay.

What's with Impreza dogging on dual-cores for? Did you pay $500 for an FX-53 instead of overclocking a wee 1.8ghz A64? Crysis on a single-core...are you kidding me? Do you want to play at 800x600 with no details?

With X2 starting at $61.50, it idiotic not to have one, even for single-threaded games. I went from a 3.0ghz P4 to a 1.8ghz Opteron 165 and the increase in startup and system responsiveness was amazing, not to mention multi-tasking in day to day use.
