Will a phenom II x4 965 bottleneck a gtx 570?

A new video card will definitely increase your performance but the change might not be as dramatic as some benchmarks or websites claim. Your CPU will definitely bottleneck the video card (by definition it's a bottleneck since it will run significantly or measurably faster with a different CPU) but you probably wouldn't notice it most situations.

Here's a comparison of the 965 (3.4) with the 1100T (3.7 with turbo, the situation with games). If you overclock your processor to ~4 gigs then that will eliminate the bottleneck in games.

Basically you might not notice a difference between a 570 and a 470 with your bottleneck but who cares?
 
^actually andy there is some CPU overhead for crossfire. Anyway......

Generally not too much. Of course it depends on the games you are going to play. Some games, like many RTS games, are more likely to be limited by the CPU. It also depends on the resolution and visual detail as to when the GPU becomes the limiting factor. You can of course limit the bottlneck by overclocking your CPU and as long as you have a C3 CPU and a good cooler it's reasonable to assume you will get at least 3.6Ghz with minimal effort but hopefully you get closer to 4.0.

Ok , so if I use a gtx 570 on a stock phenom II x4 965 it may result in some lost fps? Because I'm trying to ensure that if I use a 6950 or gtx 570, heck, even a gtx 560 it won't hurt my performance on that processor..I'll only be using it for a few months until I change the motherboard and processor in the summer for a sandy bridge build.

1080p preferably ...but x1050 is good as well...and yes sandy bridge is the bees-knees, I know. But I had to return my ud7 because of this recall stuff..so I need something cheap and good enough to last until summer when I upgrade..or until Christmas for the new socket. I was considering an x58 build but if an amd processor can play my games with good performance it makes sense to go with amd as a temporary fix.

Get the best gfx you can afford then.

Any Sandy Bridge i5 will easily handle any current high-end gfx.

Don't waste your money on X58. Sandy Bridge is much cheaper and significantly better. If you just can't live without X-series, then just wait for the X68 which should be released by the end of the year.

the cpu dont matter much at high resolutions. SB or X4 wont matter

http://www.legionhardware.com/articles_pages/cpu_scaling_with_the_radeon_hd_5970,12.html

A 5970 eg? Hot damn! Okay so I can use a 6970 or gtx 570 with no worries with the amd processor then! That's fantastic! I'm eventually gonna get a sandy bridge build (again) but I'll wait till some revisions for recalled boards are made and there are no more problems! But if the phenom quad core can handle a 6970 and gtx 570 then I should be okay for a few months.

I was only considering x58 because someone was giving me a good deal on the board and i7950..but if I can use an enthusiast graphic card with the amd processor then im better off spending a little extra cash on the gpu and saving the rest for the future build.

Luckily for me I dont plan on playing any of those games on this temporary set up. I'd rather lose a few fps for the short term, and get a motherboard and processor switch in a few months when this sata II debacle is sorted out.

The thing that gets me is that if the mainstream CPUs oc so well, what's x68 gonna be like? I'm thinking that's too much power its gonna be havin..what if they make a rampage iv Extreme? Anyway I appreciate everyones help! I can now purchase a great video card without any worries or regret!

Okay that's good to know..kinda broken hearted after I had to take my ud7 back! Sandy bridge was a nice taste of power...but once the dust settled perhaps there will be more surprises on the horizon. Amd will have to do for now

Yeah..I feel like dealing with an x58 as well..someone is giving me a good deal on a rampage board and i7950 as well..what to do...id like some crossfire or sli action but the amd processor Im considering getting may bottleneck...hmm..what..to do

Just get Gigabyte GA-P67A-UD7 or Asus Maximus IV extreme (after Intel fixing the SATA issue) if you want to SLI/CF gfx better than HD5870. These two boards also come with two 16x PCI-E as the X58 ones. BTW, X68 will not be backward compatible with X58 CPUs.

I only plan on playing at 1080p for now..maybe a bit less...so I'll use a 6950 or gtx 560..I hear you can oc that card to perform like a 570..all the extra money I save can go towards building a very bad ass sandy/bulldozer rig
