Alright guys, I am getting the 7950. After newegg raised the price on the XFX HD 7950, I called them and they agreed to price-match to the original price by giving me a $40 Newegg credit. So overall, it will cost me $300 - which is an amazing price for a 7950 with two fans. I'm pumped.

This is because Racing games benefit from quick VRAM. This is the same for Metro 2033 as it depends on a large bandwidth and data transfer of files.

What hell is happening here?
btw 0.2 is in margin of error, but not in heaven, i can run bench 20 times, and i will always get the same score.

Just for some comparison, my 7970 in Heaven:

Core Clock / Memory Clock ---- FPS ---- Score

1250 (@1274) / 1425 (@1600) ---- 58.0 ---- 1461
1250 (@1274) / 1800 (@1625) ---- 61.2 ---- 1541

So that boost of +375MHz on the memory netted just over 3+ FPS.

I was having big problems with my 7950..

After crashing on 72c on 1080Mhz/1500 I was browsing internet, then the GPU started to constantly crashing and then recovering. That happened like 7-8 in a row, before I managed to restart my PC.

I'm going to reinstall drivers, which are June 14 Beta.

That was horrible.. helpinghand.gif

Hi Everyone!

I wanted to share what I have experienced so far with my new MSI r7970 Lightning.

I also want to thank BradleyW for the ATI driver removal guide! Excellent work! thumb.gif

First, I purchased the card NEW from Amazon, and it was received in good condition. I did notice however, that there were no seals on the box. I am not sure if this is how they ship, but I noticed another poster mentioning the same thing.

Installation went well; I installed the card, with no drivers present on the system. I then installed the latest beta driver : AMD Catalyst 12.x (9.00 June 12). I did some testing at stock (lightning) speeds, and then installed MSI Afterburner 2.2.1. I have yet to experience any serious issues, after overclocking, Heaven 3.0, 3Dmark11, Skyrim, and BF3.

I did notice a few minor things: My 3dMark11 physics score seems to be awfully low. My overall score is just over P8000 @ 1175/1600. I am unsure if the processor has anything to do with this. Then, while testing in Kombustor, the GPU reached 85c @ 100% fan speed @ 1175/1600 (1174mV). Seems kind of hot even for Kombustor @ stock volts. This is my first non-blower model, and I may be mistaken. I will try and adjust my internal fans to see if it helps. Also, The very first Heaven run I did at stock clocks, was riddled with artifacts. This was the initial display and disappeared after I ran the benchmark. I have run it 3 times since and have not seen it again.

As for performance, It is quite an improvement coming from a 5850 (w/5870 BIOS @ 850/1200). It is dead silent up to about 60% fan, this is when I begin to hear it over my case fans. It does not even reach this level while gaming, all while always staying under 60c.

So far it seems to be a fantastic card! 50+ FPS in BF3 on full blast, Skyrim is as smooth as silk (I think a mod is blocking my OSD, and I have yet to see memory usage), all while being much cooler and quieter than my previous card.

If anyone has any suggestions, critiques, or comments regarding anything I am posting, please feel free to comment.

The Spoiler below contains pictures, and test results that I have compiled thus far.

Thanks all, and Cheers!

I cant seem to turn up my voltage at all. Its odd because afterburner shows my voltage going up as i adjust it but open HW monitor shows the same 1.17 all the time. If this were true id be at a happy 1285 core on stock voltage ( A guy can dream). Which one would be showing the correct voltage?

If using afterburner to change voltage then use afterburner to track voltages as well. Running ab and hwinfo together will cause incorrect readings. If I use ab and gpuz or hwinfo my voltages always stay at 1.175 as well.

The physics score in 3Dmarks11 is all to do with CPU.

No cherry picked silicon for the lightings, yours is not the first lighting I have seen with low ASIC

this card is a fantastic overclocker with very good memory overclocking too. comes with dual BIOS. the 2nd BIOS allows aggressive overclocking. With sapphire trixx and voltage tweaking this card can do 1250 Mhz . here is a review

This card is also available at a very good price of USD 480.
