Radeon 4850 to 5770. Worth upgrading?

I`m getting a new monitor this month so I will be gaming at 1900x1080 full HD res. My current card is a 4850 (the 512mb one) and I don`t really know how will it perform at that resolution so I might have to consider my GPU too

So now I have a couple of questions:
Will the 4850 give me playable fps at 1080p? (anything above 30 is OK, for me)
How well will the 5770 perform at that resolution?
How much faster is the 5770 and is it really worth upgrading or should i wait until I save more money or any new video card comes out and if it isn`t worth what GPU do you suggest (ATI cards only, price not higher than 200$)

My CPU is an Athlon IIx4 630 at 2.8 Ghz (default speed) and my PSU is an ARCTIC POWER A-600DX 600W. There should not be any bottleneck/power issue, I think

I will be gaming mainly Crysis, Resident Evil 5, Modern Warfare 2, World in Conflict, DIRT 2 etc but I also want to be sure my PC will handle future games (Crysis 2, Black ops, Kane & Lynch 2, Dead Space 2)

IMO it's not worth upgrading. Do you have a Crossfire board? I'd add another 4850


Yes, but unfortunately the second slot operates at x4 only. I`ve heard that x16/x4 configurations are sometimes slower than a single card and that the second card would be a waste of money

i agree with pyscho, unless you get a great sale price the upgrade is not a big leap.

I've never heard of it being slower than a single card. There may be performance loss, how much I can't tell you, but I know it won't be slower than a single 4850.

+1 for adding another 4850

megamanx00 has valid point (MegaMan rulez btw ;)  )

Well, lets look at what is specific to original poster.

What motherboard do you have?

That way we can outline:
1. Whether or not you have PCIe 2.0 or 1.0.
2. Whether or not you can switch your PCIe lanes to 8x8 or if they will only operate in 16x4.

In case of 1, and if you DO have 2.0 you should be fine not matter the lane configuration (as 2.0 is double 1.0 bandwidth, so 4x 2.0 is equivalent of 8x 1.0 which is plenty of bandwidth)

And in case of 2 and you DONT have PCIe 2.0, if there is the capability of switching both slots to run 8x... you'll have enough bandwidth regardless of PCIe version.


So, what motherboard do ya have? and we can help you make the best educated decision.

My motherboard is a ASUS M4A77TD PRO
Chipset is an AMD 770 but i don`t know if it is PCIe 2.0 or 1.0

yes the Ati 5770 is well worth it if you want all the new feautures of the new generation cards(Noticably Dx 11, open gl 3.1 and Eyefinity).

Going from a HD 4850 to the HD 5770 is basically an upgrade to the HD 4870 + DX11 and lower power consumption.

- In terms of performance, it is not worth it. The performance gain is too little to justify the cost.

- For DX11, it is not worth it. There are not too many DX11 currently. They will be coming out in the future. At that point you should be able to afford more of an pgrade if you save money.

- For lower power consumption, not worth it unless... you really care a lot about the environment and you want to start reducing your "carbon footprint".

Thanks for the help. I`ve decided not to get the 5770

However I still don`t know what to do.

The performance gain by adding another 4850 in x4 mode was only 13.7% in Crysis. I wonder if an x16/x4 configuration will be able to match a single 5770

Anyway the 4850 is still a pretty good card and I don`t mind waiting a couple of months. I might just consider getting a 5830 or a 5850 or just wait for new Radeon GPU`s

Your board is PCIe 2.0. Which means 4x 2.0 is like 8x 1.0 performance. So go ahead and re-look at the reviews and benchmarks at 16x/8x.

TBH I think another 4850 would do right by you.

Quote:
The problem is, in some cases crossfireing with a 16x and 4x setup results in odd performance. This article is a little old but it's relevant to you since it specifically singles out the 4850

http://www.legionhardware.com/arti [...] son,1.html


The p35 board used in this link mentioned prior is PCIe 1.0


Keep that in mind, you have double the bandwidth.

*edit* another to consider, you can OC that athlon 2 x4 of yours and get a nice speed bump all around.

x4 doesn't cripple a 4850 all that bad, the 4870 really is the starting point for crippled performance via x16/x4 crossfire. Also, going by crysis alone is not accurate. There are very few games with the dual dependence of crysis (CPU+GPU limitations hah) so the system resources needed for running multiple cards is taking away directly from performance.

Yes, an x8/x8 setup will perform better than x16/x4, but it will probably not be that big of a difference in this part of the GPU spectrum.

i`ve seen a benchmark when a radeon a 4770 (which has very similar performance to the 4850) was tested on both intel core I7 Extreme and AMD AthlonX2 7850 on Crysis and the difference was less than 1 fps. Crysis is entirely GPU dependendent. That`s why I`m using it as a reference game

And I don`t know how to overclock my current CPU. I`m not new to overclocking but the clock multiplier is locked and last time I tried to change the other values in BIOS I experienced a series of shutdowns and system failures
