I5 2500k+GTX 570 vs phenom 955+GTX 580

[Matt34533]

As the title says, I'm trying to decide between the two for my new build. Both cost $800 with the rest of my parts.

I game at 1080p and want to be as future proof as possible.

I play shogun 2 and BC2 and will be playing bf3.

Also, what the minimum powersupply for a 580?

I would definitely head toward the Intel architecture first, then consider the video card.

Get a 2500K and 570. I'm sure the 570 will run great with BF3. You can always get another one later.

Thanks ubercake. I just saw the Galaxy gtx 580 for ~$400 after rebates and was trying to resist.

Make sure you get an SLI capable motherboard:

so you're ready for another 570 one day.

Yeah, I have the MSI p67a-g45/i5 2500k combo that comes out to $300.
Quick question. The Coolermaster GX 650w will be able to power the 570 and i5 2500k with some overclocking correct?

 

[ubercake]

Sure. But if you plan to go with an SLI setup at some point, you'll need at least a 750W. This one's under $100:

But this is one area where you really don't want to cut corners though. I'd recommend this 750W supply:

Also, you'll find you won't need to OC much of anything to get good frame rates with that 570.

 

[Matt34533]

I would definitely consider the 750w if it would power 2 570's. It will?

Here's info on the power consumption running 570s in SLI:

They recommend more if you'll be overclocking. Seriously, though, I don't overclock my i7-960 or my 580s and my GPUs reach full load at times while gaming. If you aren't running old games or everything in 1024x768, you won't have to OC anything to get peak performance out of your 570s. When you OC, you always have some unknowns with the requirements. I don't do it, but people say you could require an additional 100W+.

The most my system has required while gaming with the GPUs pegged was just around 670W with no OC.

Your system would require around 20W less per card (-40W) and 25W less for the processor with no OC putting you right around 605W. Add OC to your components and you'll drive the power requirement easily to the edge of what the 750W can provide.

My recommendation if you're going to OC the video and CPU would be to bump it up again to a Corsair 850tx:

It's only $20 more than the 750TX, but will give you some wiggle room to OC even when you have two 570s. All in all the 850TX will give you around 200W of overhead (once you have 2 570s) for OC'ing things.
