AMD FX processors released

[Libertas Computers]

The problem is...it isn't all that much cheaper than Intel, and the performance is so wildly variable whereas SB performance is quite consistent across the board. You can get a decent ECS dual card Z68 board for like r8-900, and a 2500k for r1600, and that's plenty cheap and plenty powerful. One possible winning scenario is if Bulldozer is truly backwards compatible with older am3 boards in which case you wouldn't need a 990FX which is very pricey by itself. Then you could sell your current cpu and pop in an 8150 or so and get a decent upgrade for quite cheap.

Hence the above post.

All I'm saying is that I don't feel the 8-cores, maybe even the 6-cores is needed for a gaming rig at the moment. I think that's more in the line for serious multithreading and I'm hoping for AMD's sake that that issue can get sorted.

Perhaps you'd lose some performance running a 8-core CPU on a non 990 chipset, but I doubt the same can be said for running the FX-4100 on a previous motherboard.. I might be wrong, but that's what I think..

it is confirmed that it does work, some guys running msi 890fx and asus 890fx on XS forums, without any problems.

just a bios update and your sorted, wanted to go for the msi 890fxa-gd70, seems you cant get them anymore, wanted the dual lan

Cool, any word on 790 and back?

You only need a strong cpu when you running two bulky gpus or a very low resolution for gaming. High resolutions its all on the gpu.

It differs from manufacturer to manufacturer.

Asus for example states that the M5A78L motherboard supports it and that's a 760G chipset.

Sure?

bf3 owns my 2500k, running at 5ghz, 80% + cpu usage o.0

The low resolution stuff is competely wrong. When you see higher CPU usage at a lower resolution, then that is because of an increase in framerate, i.e. the CPU having to feed the GPU more frames. If your framerate is locked (e.g. vsync) then you won't see any increase in CPU usage when you drop your resolution. If your CPU is a limiting factor, then it won't be more of a limiting factor at a lower resolution, because your framerate will never go lower than what it will be at a higher resolution.

In any event, what you need for most games (and why BD's gaming is pretty lacklustre) is single-threaded performance, since rendering is largely serial (unless you have multi-threaded rendering under DX11, which BF3 may have).

Firstly that's nonsense. Secondly who cares? For the same dollars you want to buy the fastest CPU that you can buy. Saying it doesn't really matter in most scenarios doesn't matter one bit.

Yup, what about the future. Perhaps you buy amd because you don't need much power and 5 months later you decide to buy a decent graphics or two and now you must upgrade your cpu again.

Sounds like a bad plan

Sorry for the bump, but we received a lot of request regarding when the CPU will finally be available in SA and it's pricing.

It has now slowly but surely started becoming more and more available lately. Pricing differs from what I said earlier in the thread, but not by that much. The price should come down a little bit as more suppliers' stock arrives.

I for one am still waiting it out with my Phenom II (tri-core), but even after watching all those reviews and reading everything I've read I can't decide if it is worth going Intel...
