Wouldn't it be better to use amazon.de (or maybe amazon.co.uk ) for you, if you live in Europe?


Besides that: I'd take a real GTX 560 TI, not the GTX 570 SE (for slow edition), wich the 448 'Core' Version is...

Exactly. Avoid amazon.COM and use amazon.co.uk or .de ... There's even a .fr one but I generally avoid it because you usually get "french-ified" products (french manuals and so on)

For some countries (including mine, Romania) the .COM version will only allow people to use the expedited shipping option, basically courier. Yeah... like I'm going to pay 40$ shipping for a 60$ product...

In regards to how much power you need, video card manufacturers usually say a minimum because they can't possibly know what power supply you'll eventually buy.

There's plenty of cheap power supplies out there that are based on old designs, from the times of Pentium 3 and Pentium 4, which means they were made to provide a lot of power on 3.3v and 5v and little on 12v.
Nowadays, the systems use 12v for both the processor and the video cards, so such power designs would be unable to provide enough power on 12v.

By saying 550w or a high value, they're just making sure a customer buys a relatively modern design of power supply.

A video card is allowed to draw around 60 watts from the pci express slot and about 75 watts from each 6 pin pci express connector. 8 pin connectors increase that limit to - i believe - double the amount, but in any case the video card is not allowed to go over 300 watts pulled from all power sources.

The video card you linked to has 2 6-pin connectors, so overall it shouldn't draw more than 200-230 watts without overclocking. That's 230 watts / 12v = 19A of power.

The power supply advertises 48 A on 12v so even if your system uses 19A for video card, and about 10A for the processor and other things, you still have a lot of room left for overclocking and messing around.

ps.. just realized i posted to a thread revived after four weeks...

Really? All reviews show the 560ti 448 as much closer to the 570 in performance than to the 560. I happen to have 2 of the MSI TwinFrozr's that I got when Amazon had them on sale: they're very nice little cards and the best you could do price wise at the time. Now, a few months later I'd wait and see what 660 prices are like or look at the 7850....but a 560 448 is a big step up over a 560.

GTX560Ti 448sp is basically an overclocked GTX470. No wonder it does better than GTX560ti, since GTX560Ti and GTX470 have similar performance.

I have a pair of the 448 core cards, and they are fine cards. And yes, they are a cut down GTX570, but they're a fine performer.

I don't like 448 Core Version, because the power consumption is closer to the GTX570 than GTX 560 TI.

The 448 core is worth it if it is priced right, and that has to be a significant discount vs the GTX570. If the price of a GTX570 is not much more, then plainly the -448 isn't worth it.
