So, Black Friday coming up, and I want to get a new video card. Some quick questions: Will my current power supply accommodate the additional watts needed for an EVGA GTX 580? (Dumb question, asking it anyways)
Second question is, will my CPU bottleneck the 580? My i7-950 is only a 2 year old processor, and a pretty powerful one at that, but I've gotten into the habit of running it at stock settings again (mostly because I dislike the hassle of having to find what's causing a certain problem).
I know many people will consider this upgrade to be kind of meaningless, considering that I already have a GTX 560 Ti, which seems to be having issues with BF3, running it rather poorly. In addition to that, GTX 600 series cards will most likely be coming out in a month, with my main concerns being the price of those cards, with a 580 still around half a $G.
So yeah, just some quick questions before I end up making the purchase.
The Corsair HX Series 750w in your sig, if that's what you mean, will easily handle one 580.
As for the 560 performance in BF3, have you tried the 285.79 beta driver?
I'm not sure you're right that the next model series of Nvidias will be out this year. All indications have been that their 28nm GPUs won't be out until well into 2012, like spring at the earliest.
AMD's 28nm GPUs are supposed to be out by year's end, with talk of Nvidia releasing a 448 core version of the 560 built on the 570/580 GPU sometime soon.
Yeah, I figured the 750w would handle a 580 no problem. Just wondering if I was missing anything in that department.
I am indeed running the beta drivers. Currently running most things on high, but I can't use HBAO or AA deferred, as it drops my FPS to what I consider unplayable (under 60 frames).
I just assumed they were going to do the whole yearly release thing, however if I were in their shoes I'd wait until PCI 3.0 becomes more accessible. From what I heard, IB is going to stick with 2.0/2.1, so I wouldn't see any point in it. Also the reason I'm getting the 580 and not waiting until there is more information out about the 600 series cards.
I've sworn away from AMD. I really dislike their driver/driver support. Goes back to a problem with a game they supported forever not getting any support for 9 official driver releases.
1. Better to go by whether you actually detect any lag vs insisting frames be at or above 60 FPS (BF3 plays pretty well at 40 or even less)
2. It will be SOME time before GPUs even saturate Pci-Ex 2.0's bandwidth, let alone 3.0
3. Totally agree on A camp's driver support
There isn't really lag, but frames aren't consistently above 60, which is what I'm looking for, and I have to use pretty funky settings for this card. I found it strange that an i7-2600k/HD6850 could run BF3 better than an i7-950/GTX 560 Ti. They should technically be running around the same.

My Corsair TX750 power supply runs my GTX 580 with no trouble. And it blows BF3 away with everything maxed out.
AMD cards run frostbite engine games a bit better than nvidia cards. My gtx580 always had smoothness issues (fps spikes) compared to when I ran a Radeon 5870.
Also take into account that the engine likes the raw horsepower of the 2600k more than the older architecture of the 950.
For your PSU, you can run two gtx580s on that thing and be fine.
They actually just fixed the stuttering with the latest patch. I used to get horrible stutters with my GTX 560 Ti, which were lessened by the Nvidia beta drivers, and fixed completely with Tuesday's patch.
Anyways I don't think that any of these issues are processor based. They seemed completely graphic based.
My 950 bottlenecks my 580 in a couple of games. Deus Ex being one. If you OC it a little you should be fine. 3.6GHz should be plenty.
Didn't think Battlefield 3 was all that processor intensive. Seemed like a graphic power whore to me. Either way I guess we'll find out, I can always OC a little bit, I just don't want to go to extremes to get it running on par with the new card.
