i7 2600k
P8P67 Pro B3 MOBO
GTX 460 2GB
8GB G.Skill Ripjaw X Series RAM
Corsair 650TX PSU
1TB Seagate HDD
Antec Illusion 300 Case


That's my current build but now I'm looking to drop the single 460 and pick up a single MSi 580 lightning. Can my PSU handle it? Can my PSU handle any 580?

Nvidia recommends a 600w psu http://www.nvidia.com/object/product-geforce-gtx-580-us... so in theory the 650w should handle it. But considering the Lightning is overclocked and by the looks of your build you might be overclocking I would recommend looking at getting the Corsair TX750 for stability. Also why are you picking the 2600k over the 2500k or have you already bought these parts?

my cousin works at Intel in norcal and got me a i7 2600k for $169. so i just picked it up. i won't be overclocking. i've had some bad experiences doing it :p  so if i don't overclock i should be set? funny, i asked this self-proclaimed pc elitist on twitter and he said it wouldn't be able to handle.

Don't listen to the above post; obviously clueless about PSUs. Total power consumption even overclocked will be less than 500 watts.

In fact don't listen to anyone who goes by the nvidia's recommendations or uses a PSU guide. Better yet get your answers from overclock.net

Well aren't you a lucky duck, jk that is a very sweet deal on the 2600k. I am just quoting Nvida's website and in no way claim to be a pc "expert" so take my advice at your own risk. Also Antec's power calculator says you should be fine with a 650w http://www.antec.outervision.com/PSUEngine

If you aren't a PC expert stop giving PC advice and let the real experts do it?

Please explain how you are a pc expert? And how do you assume I am not knowledgeable about pc's. I apologize to randethan for going off topic in your post, but this dude is being ridiculous.

I'm more of an expert than you obviously or you wouldn't have suggested that the 650W PSU was cutting it close.

its fine. i went to overclockers.com and looked at a thread. one reply said get a 750 but most others said even a 550 could handle it with an i7 running. i think im ok because i wont overclock anything.

If you're buying a card new you don't really need more than GTX 560 Ti for a single 1080p monitor. That being said the 580 is sufficient to handle XHD.

No; but if you SLi 460s they will outperform the 580 at 1080p and below if you overclock at all.

BF3 is using FB3; FB2 runs extremely well on a single 460 even with most eyecandy on for BC2. I doubt the requirements for BF3 will be much more than BC2 especially since it will be released for console since that's where they make the most money.

Probably not because that takes up some high voltages and most likely if you have that in your rig than your going to have other higher end products with mid-high voltages

yea i wasnt gonna sli, was just curious lol. i'm probably gonna sell my 360 and 460 to get the cash for the single 580. my aunt at palit is asking me whether i want the 1536 mb model or 3gb model. whats the main difference? is the 3gb gonna need A LOT more power to power it with a psu? yes i game on BC2 but since BF3 is going to have 64 players and constant explosions i want persistent smooth gameplay. idk, from what i hear you need a 580 to max/come close to maxing it out smoothly.

From what I know the 3GB version doesn't have the proper VRM and cooling for the RAM and should be avoided.

More RAM helps primarily at higher resolutions (since there's more pixels/textures) such as with multiple monitors. For 1080p 1.5GB is much more than you need. If you do happen to use more than 1.5GB of VRAM the GPU itself will be much more of a hindrance than the RAM (that's really saying something with a 580). The 1.5 GB version is just as fast at pretty much any reasonable resolution even with multiple monitors.

If you are willing to part with the XBOX and the 460 to get the 580 then it's a pretty good choice. Honestly it's kind of overpriced and should be around $400. If you're hung up on a single GPU you might want to consider the GTX 570 or HD 6970.

I will probably be selling my XBOX and 460 a couple weeks before BF3 drops in. Then order the 580. Hopefully by then the price will drop and combine that with the discount amount I can get. Thanks!

lol, you are such a troll.

-going with what nVidia recommmends is a good idea. Just to be on the safe side.
-BF3 runs on frostbite 2.
-You're insulting members for no reason, adding to my conclusion that you are a troll.

OP: you would probably be better off getting another 460 especially if you can get a discount. See how much the Palit 460's are with discount.

But totally sell that 360 :p

Don't listen to this fool; he obviously needs a PSU calculator which makes him ignorant about PSUs.

I was wrong about the FB engine slightly; BC2 uses 1.5 while BF3 uses 2.0. Either way it's the third version of the engine and should have similar requirements.

I insult the computer illiterate who "try" to give computer advice; unfortunately that's half of the forums here.
