so i currently have a Radeon HD4850 512MB and it hasn't failed me yet but i do want to have a DX11 card for Dirt2 and Bad Company 2 (pre-ordered on steam :D  ). my question is: is the HD5770 a good upgrade (im loving the price tag on it) or do i have to save up some cash to grab a HD5850? this would probably make the question easier to answer once i say that i play on a 1280x768 resolution screen.

More about : dx11 card

A 5770 isnt much of an upgrade, and the 5830, the right 5830 may be what youll want

5770 is an upgrade, it runs like a 4890, and when you OC it and put it into crossfire it runs like a 5870. My advice for this generation of cards is to buy the mid-range card and crossfire it, as this gen seems all about multi-gpu.

hmm.....interesting but i don't have the cash for mutli-gpu or even the PSU for it either so if you can pick one card for an upgrade to DX11 on a 1280x768 what would it be? the 5770?

The 5770 is 25% faster than the 4850, which I believe is a decent upgrade for $150.

Nevertheless, you play at such a low resolution that the difference will be minute and irrelevant in DX9. I recommend saving for a bigger monitor and then looking for a new card.

If you really want DX11, then a 5750 or 5770 should be all you need at that resolution. Here are the results from DiRT 2, which seems to utilize DX11 very poorly and does not have any of the performance boosting functions, so it is a worst case scenario.

Notice that is with everything maxed an 4x AA at your resolution. The 5750 manages to be perfectly playable and likely very smooth with a minimum FPS of 30 FPS.

Whether any of this is worth it is completely up to you. I recommend waiting to see just what bad company 2 brings to the table before pulling the trigger.

Hope that helps.

At your resolution you shouldn't be considering an HD5830. It is extreme overkill and a waste of money.
The HD5770 is about 25% more powerful than the HD4850 but I'm not sure you will see much of a practical difference at your resolution as the HD4850 should already be really good. It is your best choice though if you want a DX11 card.

My reasons for the 5830 is because my belief is, if youre upgrading, it should be more than 30%, so youll know you have a difference, not just in current games, but future games as well.
Its still up to the OP, but going by Cleeves recommendations, 3 tiers is whats needed, which I agree with, which is usually 30+% IMHO

You can't just stick to a rule blindly when it doesn't make sense for the situation. The guy is using a 1280x768 monitor. The HD5830 is just pointless unless he upgrades to a higher resolution.
As for the 3 tier rule in general the tiers are not uniform, especially near the top. 3 tiers up from an HD4850 is the HD5870 and the performance difference is massive, nowhere near 30%.

Its more the 30%, as 1 doesnt make the other, or 3 tiers isnt always 30%.
But 30% is what I look for personally. If you go sideways, its not alot, other than DX11 itself, and Id have to ask the OP how long he intends to keep his card, as new games come out requiring possibly higher abilities.
Its just a more forwards looking solution, but, to each his own
