    And GPUTest Furmark is unusualy slightly better on 7850 with radeon then with fglrx 2217 vs 2109 .

    Is this because of different CPU used or?

    So if I wanted to buy an entry level AMD graphics card for use with the opensource driver, what's the best option in the $100-150 range? The 265? I know there's a few radeon driver devs around here, would be nice if they could lend an opinion

    Seems like But depend is it straight at $100 range or $150 You can get R7 250X for $100, R7 260X for $120 and R7 265 for $150 .

    If you happen to have an FM2 motherboard Kaveri might be interesting for you. Its what I'm going with personally, and then probably upgrade to Carrizo next year. $170 for the new A10-7850k, comes with R7 260 based graphics. Of course if you have an Intel board then this doesn't work out, but if you happen to already have an FM2 CPU then it might be interesting to check out.

    Couple of quick tweaks, probably what you intended to say anyways...

    1. you need an FM2+ mobo to run Kaveri, not FM2

    2. Kaveri graphics are the same architecture/generation as R7 260/X but has fewer CUs and runs at lower clock speeds... so 250X and higher dGPUs should all be faster

    Just keep in mind that APUs are different, it has R7 based graphic chip but APUs have different bandwith and core config then discrete cards so it is expected to perform like entry/middle level R7 discrete... in real world tests A10-7850k graphics perform somewhere in between R7 240 and R7 250 discrete cards and if those two have GDDR5 then what will happen But no way that someone can expect from A10-7850k to have R7 260 performance of discrete card . Just my 2 cents .

    Whoops, thanks for catching that Bridgman. I really need to stop trying to post from my phone -.- Because it never works out well. And true, though the clock speeds issues is slightly mitigated by the fact that a lot of users are getting very stable overclocks to over 1ghz for the GPU on Kaveri. Still not -exactly- the same but it does help. Personally for me getting a dGPU would be overkill anyway as most of the games I want to play are "Last gen" like Mass Effect / Dragon Age and are only at 720p. Also I want to see what AMD is gonna be putting out when it comes to GCN 1.3 / 2.0 before I drop $100-200 on a dedicated card.

    Slightly on / off topic, to all the AMD guys in the forums... grats on Kaveri Got a MicroATX build coming together for a slightly overclocked integrated-only microATX build for light to medium gaming and i've only heard good things about similar builds. I know some reviewers gave Kaveri a couple docked points because of CPU performance in some cases, but I am very much looking forward to dropping in Carrizo next year and seeing what AMD can do at 65TDP and Excavator.

    Anything that runs on r600g. So a new 6xxx if you can find one, or a rebrand of such.
