Would my CPU bottleneck the 570?

No. But if you could sli those 460's you would get a huge boost, much better than the 570.

I have a 768MB 460 and have had no problems gaming in 1080p. The 570 is a faster card obviously but unless you push your resolution higher it's a moot point.

A few problems with SLI for me:

1. My motherboard is a radeon chipset, Some have said I could hack it to do SLI though?
2. Second card would be running at 4x bandwidth
3. Isn't microstuttering never TOTALLY gone in multi-GPU setups? Just less noticeable sometimes?
4. I hear about a lot of problems with multi-GPU compatibility in games. Someone recently was having problems in Arma II, I believe.


If none of these are valid problems, please tell me though, I'm not claiming to know a lot.

You're right, but if you are going to upgrade it wouldn't be smart to buy a 570, as most of them don't have enough VRMs and the performance increase would not justify the cost. A 580 would be a better upgrade coming from a 460.

How much the CPU bottlenecks the GPU is always dependent on the testing scenario that you set up in order to detect the BN effect.

With your CPU and a 570, when running the more cpu-dependent games out there (GTAIV, BFBC2, and Crysis are examples of games that require quite a bit of CPU power per frame rendered) , it will definitely be the case that you'll get a lower FPS than someone who has a more powerful CPU. There are also plenty of gaming scenarios where you'll get the same FPS as someone with a 570 and a Sandy at 5.0GHz.

The absolute worst case scenario if you did this upgrade is that you'd end up getting the same FPS you get now, only you'd be able to achieve that FPS with considerably higher graphical settings. It's unlikely that you'd experience the worst-case scenario very often though.

This all being said, the Athlon X4 chip does leave a bit to be desired in the gaming department. Any chance you could sell it and grab a PHII quad?

Isn't the athlon II X4 only like 10% weaker than a phenom II in games?
