GTX 460 768Mb vs HD4890 1GB
Basicly i have the chance to swap my HD 4890 1GB for a GTX 460 768Mb....from what i can find out the 465 768Mb is actualy a better performer than the HD 5830....so would swapping my 4890 1gb for the 460 768mb be a good deal?
Its DX11,better features...uses less power,runs cooler!
and before anyone says,get the 1gb instead...i cant,Its the 460 768mb vs 4890 please!
The 460 is better than the 4890, but I wouldn't go for such a trade unless it did not cost u anything. Its too much of an horizontal move, but if you can do the swap for really cheap, then sure.
depending on the resolutions you use/would like to use, the 1gig version might be a better buy/trade, even if its xx more expensive.
like i said,cant go for the 1gb model...its either the 768mb version or nothing.
but these oc pretty well soo....http://tpucdn.com/reviews/Axle/GeFor...es/perf_oc.gif
I don't know a lot about the 4890 but I don't doubt it's not far off from the same performance as the 460 768mb. That particular review of the 460 768mb that _dangtx_ linked does really seem to put the 4890 on equal footing with it.
How much does your particular 4890 OC? I own the Gigabyte GTX 460 768mb and I got a 30% OC on it, from 675mhz to 875mhz (MSI Afterburner software; which allows you to overvolt too... and I've got it overvolted as much as possible (which does NOT add much heat, the HSF handles it fine at 55% speed and is still whisper quite)).
Considering your resolution of 1680*1050, you are much less in need of the extra memory and memory bandwidth that your 4890 has.
So, I am confident you will get a very slight increase in performance except in those rare cases where a game really favors ATI over Nvidia. Usually driver updates levels that out.
I agree with Kilauea that it's a fine move as long as you are spending next to nothing to do the trade.
Well currently my 4890 is Oc,d to
850Mhz Gpu clock
I couldnt overclock it anymore because i cant adjust the voltage anyway.
Well, I just did a google search and found two sources citing the stock clock speeds of the 4890 as 850mhz core and 975mhz memory.
So that sounds like 0% overclock. If so, I'd definitely go for the 460 cuz you should get at least a 20-25% OC and it uses way less power, ESPECIALLY on idle which is the majority of a GPU's time, and it's whisper quite in any situation.
As long as your not trading the 4890 + gf for the 460 :P
Sorry ive just noticed that my clocks got defaulted back when i changed some settings earlier....my actual stable overclock is
Wow. For being two years old, the 4890 is a beast.

Surprised to see the load power not being that different, although idle temps and load noise is quite noticeable.
