I am not an expert on AMD cpu's, it looks like that is a Quad core, so as long as the speed is anywhere near 2.8 Ghz or higher, I would say that you should be fine.
I mean, the GTX 460 SLI setup, is rediculously powerful, but at the same time is very cost efficient, so even if you are getting *some* bottleneck then it is acceptable because how cheap the cards are.
It also matters what resolution you will be running, if you are doing a mild resolution of 1680x1050 then you will of course be limiting the ceiling of your setup, but you will get playable fps in every title.
thank you. So that means I can use an Athlon II x4 640 with GTX 460 SLI setup and later on upgrade to a Thuban processor.
You were talking about the resolution. I will just be upgrading the monitor to a 1680*1050 resolution. So does the GTX 460 SLI show any better performance gains when compared to a single card at 1680*1050 resolution.
ok what I will do is, I will just go with a single GTX 460 for now on a 1680*1050 monitor, keep it for 2 years and later on add another GTX 460 on my sli motherboard. So within the span of these two years, there would be games that would require SLI even on a 1680*1050 resolution.
yeah, I like it, but keep in mind, two years from now getting another 460 for SLI will seem like a poor choice for an upgrade, in two years there will be other cards the same price that the 460 is at now that will probably double it's performance.
IMO never plan to 'SLI in a year or two' it doesnt make money sense.
For a single GTX460 no, however if you are able to dig a little deeper try and look for a C3 stepping Phenom 2 quad (95w), there is a reason to want a cpu that has a unified L3 caches when each core has a discreet L2 cache. The problem is when each core is needing data and with cores are snooping data from each others cache it has a mirroring effect that waters down performance by a margin in certain apps and games. Beyond that for a single it is not a bottleneck however for sli it will be for lower res.
The thing is your resolution isn't high enough to warrant SLI considering a card like the GTX 460 is so reasonably priced and capable. It is a nice upgrade path to have though in case you upgrade your monitor or perhaps decide you want to try triple monitor gaming, 3D gaming, ect.
I am planning to use two GTX 460 Amp editions on my ASUS M4N75TD motherboard (SLI).
I still have to buy a processor for myself. Please tell me if an Athlon II x4 640 be a bottleneck if I am trying to use SLI with two GTX 460 Amp editions.
the term of "bottleneck" did only back in pentium 3/pentium 4 era. unless you're talking about quadfire or quad sli of gtx 580 and 5870 which would require core 2 q9xxx or above to handle it. otherwise even modern low end dual core cpu can run gtx 460 sli no problem.
That isn't so. Whether or not there is a CPU bottleneck will depend on the specific game, resolution and settings. There are games where even a 4ghz i7 will bottleneck something like SLIed GTX 460s even at high resolutions.
The Phenom II and the Athlon II are actually the same processing core. The Phenoms have L3 cache which can make a decent difference depending on the task, including gaming. There are a lot of games that still use just 2 cores and gaming will probably be the most intensive task you regularly give your CPU so I would take the L3 cache over the 4th core.
Here is a comparison of the two processors you are talking about; http://www.anandtech.com/bench/Product/83?vs=122
They are basically tied in the overall Sysmark score and the quad core wins in most of the rest of the benchmarks because the tasks are highly multithreaded but if you scroll down to the gaming benchmarks the Phenom II x3 wins all 4 games they have listed.
Now that said all of the above will likely be irrelevant because the Phenom II x3 is actually a quad core processor with one of the cores locked. Most current motherboards(including yours) can attempt to unlock the 4th core in the BIOS. The odds are quite good(about 75% from what I've seen) that you will end up with a Phenom II x4 anyway.
