I was planning on upgrading my graphic, from a 5850 to a 'Sapphire TOXIC R9 280x'

and overclock my Phenom II X4 965 processor to around 3.7-4.0Ghz - while, of course, upgrading the stock cooler to a lovely Noctua NH-L12.

I've been told that my CPU will bottleneck my new gfx.. is that true? even though i oc my cpu?

I have little knowledge regarding CPU's, so please enlighten me.

- Thanks in advance.

u may be bottlenecked if u oc ur cpu to 3.8 or 4ghz u should be fine

yes. you cpu is too old for something as powerful as a 280x. consider a fx 6300 or switching to intel i5 if you got the money

clock speed doesnt do much if you inital cores are too weak. you'd need 6 ghz to match the power of an i5

Yes unless you can overclock it to 4.5 GHz. But really your should just buy an FX-8320 and wait a month for the GPU... Or the otherway around ;)

I got the cash for a new processor - but, is it easy to replace such?
and which should I get?

I got 6Gb ram, SSD and 750W power supply on an unknown Gigabyte board.

Correction - It's a GA-770TA-UD3 board.

^ You will need an AM3+ motherboard if you want a new FX processor. You can use the same ram and cooler.


I'm on a Gigabyte GA-770TA-UD3 board.

fx 8 cores not worth the money. thats why tomshardware best cpus for the month never have them. an entry level i5 is better

I agree with bouncedk, with a 3.7/3.8 overclock there might be a small bottleneck in some games. Since you are upgrading your GPU anyway, try the 'Sapphire TOXIC R9 280x' with your Phenom II X4 965 and see if it performs to your expectations. If it does , great. If not get a stronger CPU. You may find that the GPU is all you need to improve your gameplay.

Thanks for the answers so far guys.

But, it's apparently only a AM3 board, and not AM3+ compatible, so I'm quite limited if I proceed to find a CPU.

Any AM3 compatible suggestions?

You already have one of the best AM3 processors. Just overclock it.

I'll buy the R9 280X and the CPU-cooler I've been looking at, overclock the shit out of my Phenom II X4 965, and then see how much my GPU is bottlenecked.

If it can't run anything, I'll get a new motherboard as well.

Which board/CPU do you guys recommend? And I'll need to reinstall Windows, if I get a new board, right?

Even if you get the fastest CPU currently available, it will certainly NOT always be the fastest, so a time will surely come when that "extremely fast" CPU in today's terms will be severely bottlenecking the GPU beasts of tomorrow, as more powerfull GPUs come out all the time.

That being said, going the Intel (Haswell i7 4770K) route for now is the best (and most costly) choice in terms of performance and longevity, if you're about to change both your MB & CPU, as it will provide you with the minimum risk of possibly bottlenecking your top-line GPU(s) in the future (which will DEFINITELY happen some day).

I personally recommend the MSI Z87-G45 GAMING board for Haswell:
http://www.msi.com/product/mb/Z87-G45-GAMING.html#overv...

Grab this board and an i7 4770K and overclock it and you will NOT look back.

Of course that doesn't mean that the AMD FX-83xx (or even the Phenom II) is not a good chip. In fact it's a solid performer at a very good price, BUT it is more likely to bottleneck your top-line GPU(s) in the near future, especially if you plan on running a multi-GPU setup.

If you decide to stick with AMD, any 990FX AM3+ board will do the job nicely.

As far as your having to reinstall Windows (assuming you have Windows 7 64 bit installed) with the new board, the short answer is NO, you don't really have to. The system will boot right into your Windows desktop and you will only have to install your new board's drivers and reactivate your copy of Windows 7.

However, there are folks out there that would strongly suggest you to reinstall everything from the beginning in order to get the maximum out of your new system, especially if it's been a long time since you last did a fresh install of Windows.
