GTX 670 + Phenom II x4 965 BE OC?

Last response: in Systems
Share

As stated above I have a Phenom II x4 965 BE processor overclocked to 3.8 GHz stable. I have a PCIe x16 slot for my current GPU (560 Ti) but I am wondering if you guys think there will be much of a bottleneck between CPU and GPU or PCIe and GPU if I were to buy a GTX 670. I've read that as of now, not all the bandwidth of a PCIe 3.0 or 2.0 at x16 is even used up by current GPUs, which is good. I'm just a bit worried about the processor, I'd appreciate somebody with a similar setup answering please. Also, I havn't had the best luck overclocking the CPU but once I buy some new thermal paste for the H60 I should be able to push the CPU a bit higher (possibly 3.9 or 4 GHz, maybe more, who knows.) Thanks in advance!

There was a guy asking almost exactly the same question a couple of days ago in the graphics forum. Short answer: You'll be fine. You'll get a slight bottleneck in certain CPU-intensive games, but it shouldn't even be visible to the naked eye, only in benchmarks. CPU might lag a bit 18 months or 2 years from now, but then it's time to upgrade it anyway and you can just carry over the GPU.

You should be able to get the Phenom II to 4.0GHZ without water cooling, and I wouldn't bother with watercooling on a Phenom II as they tend to top out at 4.0-4.2GHZ before watercooling becomes a necessity.

I already have an H60 on it, I bought it that way. The stock thermal paste is crap and im replacing it first. I've tried for months to overclock this chip and the highest stable I've gotten is 3.8, but it seems I've hit the golden settings in my BIOS. I might be able to push it further.

Okay.. then at 4.0GHZ a Phenom II will be just fine with a GTX 670. Is it the best CPU choice? No.. We all know the 2500k is the best gaming CPU on the market, however, with a powerful ass card like a 670 strapped to your motherboard you'll have a very powerful gaming rig regardless.
