Yup. I don't like single player games and bought the last Bioshock but barely played it. Would rather sell them if I can get $40 for Tombraider and $50 for Bioshock. Threw it up on craigslist already but will see. Rather have it cover the graphics card cost since this is most likely my last graphics card before I do a full PC upgrade since I'm still on a i5 750 but overclocked to 4.0.

Btw for those curious HWInfo32 shows this card as a 7890. Weird.

I have my card overclocked to 1200/1300 but my card doesn't have sensors for the VRM so I can't check the temp of the vrm. I don't know how hot the vrms get but the core temp is usually below 65c.

What's the graphics score you get with the regular 7870 at 1200/1300 on 3Dmark 2011? I'm curious now. Mine posted about 9367 at 1200/1500.

Memory overclocking doesn't do that much as overclocking core, so you didn't miss out much I believe by not reaching the max memory overclock of the card.

I didn't know XFX made a 7870 Tahiti, did they just release it?

Yeah I bench marked higher memory but lower clocks and it returned lower scores so I figure its better to leave memory alone and try to clock as high as possible but sucks I'm capped at this. Other 3DMark scores with the 7870XT show people clocking 1270/1670 and finishing the benchmark.[/quote]

its not a tahiti edition it is the core edition that i have and it has the same specs as most of the other cards out ther stock is 1000\1200 but it gose to about 1100\1600 and it benchmarks around the same as everyone but these cards like to heat up. I want to water cool them and then boost the speed a little more and see what happens if it is a heat isssue with mine not wanting to run stable over 1200 on the gpu i think the voltage when it is turned up is causeing extra heat when gaming and is causing mine to go belly up after an hour rolleyes.gif

I just bought the PowerColor HD 7870 LE and I love it. Kick ass card. Here are some suggestions after hours of research and experimenting.

1. Use MSI afterburner to OC and make sure power limit is set to it's highest setting (20%)
2. Set fan speed between 40-50%. At 50%, even the highest stressing will not cause the card to go above 70C.
3. Overclock the core to 1200mhz. I got mine up to 1251 stable but it would go no more.
4. Do NOT overclock the memory. Leave it at 1500mhz. My 3dmark 11 scores dropped dramatically when I tried to OC the memory.

That's it! Check out this 3dmark 11 score to see I'm not kidding...this card rocks!

Thanks for the tips. 3Dmark crashed running at 1250 so I backed it down to 1240 and it ran fine.

there is something wrong with your system. your graphics score is too low. is your overclock unstable. try running at 1200 mhz. your graphics score should be around 9800. also your physics score can't be so low because you are running i5 760 at 4 Ghz and your score is just 60% of the 2500k at 4.2 ghz.

Here is the score at 1200.
