Psu advice 2x 4870x2

madmatt10583 · 08-23-2009, 02:34 PM

Right just a quickie. I've just aquired another 4870x2. I have a coolermaster real power pro 1000w psu.
Have 2hdd's and an overclocked q9550.

Should I be looking to upgrade my power supply or would you think it's sufficent for this. Thanks

Real Power Pro 1000w is nice power supply, and it could probably handle two 4870x2s, but it's cutting it kind of fine. If you have a spare $600 lying around I would suggest getting this: http://www.newegg.com/Product/Produc...Cooling%201200 but what you have will work. Just be careful, watch your voltages, maybe drop the OC back a notch or two.

One thing. Though CrossfireX and SLI sound nice on paper, they (and I CANNOT stress this enough) are just gimmicks. A Radeon 4870x2 will handle *anything* on the market, with power to spare. Adding a second one will add little or no real performance gain. You might see a 10% higher framerate in games at most, maybe 15%. And do you really need to run Crysis at 1680x1050 at 150fps? If I were in your position I would return the card (if you just bought it) or sell it (if you got it another way). It's not really worth it, imho.

I was given it. I have noticed a very nice increse in clear sky. I will, like you say probably sell both of them when the new ati cards are launched.

But yeah, the difference to me is noticable. Not like a million fps on benchmarks but like crysis is now smooth in the ice levels @1920x1080 with 2xaa. Before, it wasn't.

As for my overclock, i'm @ 1.19v @3.8 ghz my vid is 1.2375, so that shouldnt draw loads should it??

Psu's aint my strong point as you can see
