amd x4 840 3.4ghz bottleneck radeon 5970 or 6870 CF?

post #1 of 11

Think I can still get good performance from the 840 with say...5970 video card on 1080p monitor? Or does the cpu create a bottleneck?

Yes, the CPU bottlenecks a bit, but that does not mean you can't get a good performace! You could get Great performance, just not the max allowed by the GPUs smile.gif

If you unlock the cache or at least overclock it up to 4Ghz, then you can minimise the bottleneck.

It may bottleneck the cards, but you also have to take into account what resolution you are playing at if it is below HD res (1920x1080) then you may not feel the impact so much. But if you are running at HD and higher, yea you will see a drop in performance, one card will not bottleneck the chip but 2 will certainly be on the limits, try for a higher overclock, interms of core clock speed, 4ghz and you should be fine.

Mmm no?
Lower resolutions load the CPU more than the GPU.
Higher resolutions load the GPU more than the CPU.

On high res, the CPU bottleneck will be less noticable.

What if it was paired with a 6990 @ 3.4ghz? I'm talking about 1080p.

go for broke with all the extra goodies for AA and such and you should be ok, yes some titles may drop in fps a bit more then they would with a beefier cpu but you should still get a nice smooth playing experience

My unlocked phenom ii x4 @ 3.4 bottlenecks my 5770s on certain titles, and they aren't nearly as powerful as the graphics you are considering.

Well I picked up an x4 840 with a free motherboard at MC for $100 to hold me over until bulldozer gets here basically. I decided not go with SB after all. I guess I'm just going to have to try a dang 6990 with this lil 840 and get bad fps. mad.gif What is a good overclock with the 840? Maybe 3.8?
