I5 750 bottleneck HD 5970?

Hi. I'm new to the forums and I have a little question for you :) 

Since I'm currently speculating of what I should put into my upcoming rig, I would like to know if the i5 750 @ stock would be a major bottlenect for a XFX HD 5970?

So far as I've figured, the computer is going to be like this:
- GFX: XFX Radeon HD 5970
- CPU: Intel i5 750
- RAM: Kingston, 4GB DDR3, 1333Mhz (DUAL CHANNEL)
- PSU: FH-600W
- Harddrive: Samsung/Seagate, 500GB, 7200rpm, Sata-II
- Mobo: Asrock P55M Pro

Overclocking any of the components is out of the picture (for atleast the first two years cuz. of warranty - Yes, I know it's stupid, but I've had a bad experience with me being a noob at overclocking my former cpu which caused it to malfunction and becasue I had overclocked the crap, my warranty didn't support it). Now you know why ;) 

I'll be gaming at 1920 x 1080 and since I'm pretty picky about graphics (they have to be the best) the rig has to secure that I can play games 1½ years into the future (Crysis not included) at an average of 45 FPS on maxed settings.

So I'm therefore also thinking about if maybe the 5970 is overkill? Maybe I should settle for a 5850/ 5870 and call it a day (though I'm not going to crossfire it for sure) :) 

Please tell me your opninion(s) :D

im pretty sure it will be a bottleneck at stock, but if you could overclock it a bit then i would suggest to get the 5970, otherwise get the 5870

The 5970 is a dual gpu card. So each gpu has to negotiate with the cpu/memory subsytems some games/resolutions scale up with clock speed. The i5 750 turbo's to 3.2 ,depending on the threaded load so it will keep up very well.
Its not a issue of the 1156 platform at all, in case people were wondering. The first pci-e slot should be 2.0 x16,

Okay. It seems as the i5 750 would bottleneck a little?

What cpu @ stock would you then recommend to go with a 5970?
- To give you a clue of what I'll be gaming mainly: Bad Company 2 (directX 11) & Fallout: New Vegas (when it comes out).

Actually what I was getting at with the data was the i5 750 was a good choice.

Oh I see now :)  You pretty much compare the i5 with the i7 @ stock when gaming?
- Well, is it a go then with the i5 + 5970? :D

Why dont you OC?
3.6Ghz would be a safeplace to say that it no longer bottleneck a HD5970.


Because, as I started this thread by saying, if I my quote myself :D : "Overclocking any of the components is out of the picture (for atleast the first two years cuz. of warranty - Yes, I know it's stupid, but I've had a bad experience with me being a noob at overclocking my former cpu which caused it to malfunction and becasue I had overclocked the crap, my warranty didn't support it)".

I'm sorry buddy, but I'm really not going to discuss trying to overclock it now :)  - Though I will OC in approx. two years or so.
