5770 vs 4890 1920x1080 res

[GothicGhost]

Think my other thread got removed but that was my bad anyways.

Some one said get a 5770 instead of 4890.

Only bit worries me is the 128bit on higher res

And how much slower is the 5770 vs 4890

What ever one i buy i will be xfire with second card later when i upgrade the rest of my pc.

Thanks.

Not sure on the speed, but think the 5770 is appreciably slower - like 10-20%. But if you plan to add another one later - i.e. you see it as a reasonably long-term solution, it might be worth going for the 5770 for DX11 support.

a single 5770 isnt powerful enough to get the best out of DX11 so i'd say just go for the most grunt u can get for your dosh. that wud b the 4890.

 

[buttkinz]

if you want raw fps then the 4890's will be quicker, if you favor the dx11 bits then go 5770, whichever you see as more important to you either way 2 of those cards are more than enough for any game available at highest settings as long as your not using humungous monitor resolutions in my opinion, although iv never played metro, thats supposed to be the new crysis for destroying cards fps lol

Well i will be staying with xp pro until i upgrade rest of the system + another card what ever one i get.

So would that make the 4890 better option for now but later 2 5770 mite be better then 2 4890s as heat/power needed and maybe trouble getting hold of another 4890 down the line.

Thanks.

as long as you have a reasonably well ventilated case i wouldnt worry about heat issues with 2x4890's, a quality psu above ~550 watts should cope with a pair, bear in mind tho dont skimp on a decent psu, these 5770's with the system heavily overclocked made a generic 850w psu pop, tried another apparently powerful psu and that went bang. since getting a decent one the psu run whisper quiet and cool.

 

[GothicGhost]

My case is very well ventilated also adding extra one on top when i get the time to cut the case.

I will get a some thing like Corsair TX 850W when i upgrade for xfire later on.

Got atm hiper type 580w ( i know BOOM!! BOOM!! but mine has been running for years so far so good.

So really looking at the 4890 if i don't want direct x 11 untill i get rid of the 2 4890s

 

[rolypolyman]

I'm sorry but I cant see any good reasons to buy 2 X 4890 over 2 X 5770 for an advantage of a few frames per second when the 5770's have all the other advantages, DX11, less power, heat, noise.

 

[Sayso]

mmmm i wouldn't bother doing either the 4890 is still a great card and dx11 isnt worth getting rid of it for.
when its time to upgrade sell your 4890 for £100ish and spend another 100 on the 5850...or 5870 if you can stretch that far, crossfire works well in about (dont quote me ) in about 60% of games,i find it better to get the best single card you can afford (i never go over £220), unless you are gaming at high resolutions is always the best bet.
i have owned a 4870, 4890, 5750, 5770 and a 5850, the 5850 is a step above them, its the best card i have owned (i have also had a 260, 275 and 280) unless you want to spend stoopid money its the sweet spot at the moment.

 

[GothicGhost]

Dam it now i am 50/50 lol

 

[spookywillow]

yeah think im going to skip the 5770 and go for the 5850 too

 

[Kurisu Makise]

Definitely the 4890

 

[GothicGhost]

Definitely the 4890

Thinking the same i do the extra fps now that is why i am upgrading

Wish i was asleep but the joy of doing the nights feed lol

If you can pick up a 4890 second hand in MM they are bargainlicious.

A few months back I got a 4890 2gb Saphire Vapour X for £120. No where near as noisey as people made 4890s to be and runs pretty dam cool
I have seen "normal" versions go for as little as £90 so it makes sense to get a more powerful card for that sort of money in my eyes

 

[CAPTAINBUMFLUFF]

I would go with the 5770 as its more future proof dx11 and clocks well

I can't agree with people saying the 5770 are on par with 4890's they aren't, they can't possibly be. check out the memory bandwidths and texture fillrates and you will see what I mean, a 5770 isn't even on par with 4850 nevermind a better 4800 series card.

Not true at all I have gone from 4850 to 5770 the 5770 is better with far higher minimum frames.

It's no good dragging up old benchmarks on old drivers comparing those cards what you need is latest drivers same exact other hardware and whether or not the cards are overclocked from stock speeds.

2x 5770 @1ghz each how does that compare to a 5850 ? I'd imagine it kicks it in to next week no ?

The 5770 when clocked to 950 mhz + which they can all do I think is neck and neck with a 4890.

To pay anything more than £80 for a 4890 now is madness I saw them going for £90 months ago so don't go paying anywhere near £100 for one.

Have seen pristine 4890's with 2 years warranty left go for £95 months ago.

Only get a 5770 if you plan on going xfire with them though having said all that.

It will be stonking value especially if you add a second 5770 later on second hand, paid £85 for mine in a few months no doubt you might be able to bag one around £70.

 

[CAPTAINBUMFLUFF]

The 4890 without a doubt is a better card but it runs a lot hotter and doesn't overclock well. You can overclock a 5770s core to exceed that of a 4890 but you can never get the bandwidth to match. IMO if your not too concerned about dx11 get the 4890 if its about 15% cheaper if not would go with 5770, cooler and more effiecient

Here's something more recent on a new game that matters http://www.techspot.com/article/255-battlefield-bad-company2-performance/page5.html

As you can see the 5770 is like 4-6 fps behind a 4890 @ 1920-1200 and the 5770 isn't even overclocked thus overclocked it's neck and neck with a 4890.

1920 -1200 4890 = 46.7
1920 - 1200 5770 = 41.1

And the 5770's overclock like a dream doesn't even barely raise temperatures.

Thus an overclocked 4890 would then again beat a 5770. You can't compare one OC'ed and one not.
