Default 128bit memory vs. 256bit memory

I'm about an inch from buying an HD5770, I want the DX11 and speed. I also plan on CF'ing it when I get the money for a second.

Anyhow, I've seen a couple reviews that mark 128bit memory as a con, what's the difference? Is it going to decrease overclocking room? I don't even know when the memory of your video card is used that intensively though, I've overclocked mine pretty heavily before and never saw a difference :-/

Thanks

The memory interface has nothing to do with overclocking.

They marked it as a con because the 256 bit can turn over twice the data in the same clock cycle, and it is most people's opinions that they should never make standard video cards with an 8 to 1 bus to memory ratio.

It slows the framebuffer down a bit basically.

But I really don't need to worry about it, right? I'm not going to order it and think "crap, I shouldn't have gotten this because of th memory interface"?

Its a good card.

It just could have been better if they gave it a 256 bit interface. It would've cost more though.

Great to hear, because I just bought one

I probably could have gotten a card that was a tad bit faster within my budget, but the DX11, crossfiring, and various ports sold me on it

Do you plan to do any type of EF config?

I put dual 22" monitors on my brother's and its epic. You get a much improved fov in games that have support.

EF eyefinity.

For monitors, you will need to crossfire two of these to get the killer framerates.

It'll be epic though.

Eyefinity is the monitor set up thing, correct?


I plan on it.

And yes it shall be. Yes it shall

What size monitors?

I have 28 inchers. I'm actually thinking of buying a 5770 as a hold over, then selling it when I manage to sell my 4870 x2.

I want EF bad.

21.6" 1080p, 16:9

I already have one, and it's great. I want to do 3 in landscape, would be insane. I personally think 16:10 is better for multi monitor set ups, but I already have this one so meh.

Default Re: 128bit memory vs. 256bit memory

you have to keep to the same model or else it doesn't look right.

For monitors that small, I suggest just getting one really big screen and it will be a lot better.

For example, $600 can get you 3 21" monitors or a 42 inch.
For gaming, a 42 inch plasma TV would be much better because 21.6" 16:9 monitors are so short.

Think about this kinda thing.

I plan on it, I used to have a multi set up with this current monitor and a 19" HP LCD. looked terrible

I want multi monitors to do different things on each, and occasionally use them all for the same thing. Also, this one goes for $120, that's far from $600 for 3

I don't like plasma screens either. I've considered getting a bigger LCD already, but I'm all about resolution, not actual size

Oh OK, yours are cheap then.

It'll be cool. I put two 21.5s on my brother's 5770 and it is awesome, but when I put a third monitor, it just wasn't tall enough.

Thats entirely opinion though.

I do agree with the height issue, it sorta looks wacky XD

I just don't really like 2 monitors for gaming though, because the middle of the screen is right at the split, it makes dual screen FPS games near impossible lol. It would be cool to have a dedicated screen for the map though

It is really awesome for everything besides fps though.

The point was a normal dual monitor setup but I put the EF card as a bonus.

I think you could pop a cheap DAC onto the DP plug and give it a fake resolution to offset the split but I haven't tried this myself.

It helps with headshots though.

I have triple 16:10 monitors and its almost too short really.

It only works cus theyre so big.

EDIT: pic.

That is just monstrous. I just wish I had a desk like that

I think it looks sweet, although you always wish for a 3x3 set-up

3x3 isn't possible yet.

3x2 will be when the EF edition cards come out. I might do it at some point in the future.

Its easy to take the bezels off and situate mst LCDs back on their stands if you want a thin bezel. I've done it with mine, but they have a metal thing around the normal lcd frame.
